Porcupine Tree is a ProgressiveRock group formed by Steven Wilson. They are known to combine elements of rock, {{Ambient}}, PsychedelicRock, {{Krautrock}}, electronica and (on their most recent albums) Music/HeavyMetal into their music. Many critics have hailed them as the modern day PinkFloyd when their popularity increased in TheNineties, but Steven Wilson has expressed his dissatisfaction with this label, preferring that Porcupine Tree be known as "the old Porcupine Tree" or "the new Porcupine Tree".

Porcupine Tree started off in 1987 as a psychedelic/space rock band with only Steven Wilson, who was signed to Delerium Records after a period of distributing his own cassettes and passing off PT as an old forgotten FakeBand, like SpinalTap. On Delerium, Wilson released two and a half albums [[IAmTheBand largely recorded by himself with overdubbing and drum machines]] (some songs on ''The Sky Moves Sideways'' were performed by all the band members) before turning PT into an actual band. Their fourth album, ''Signify'', was their first album where all the band members played. Their next album, ''Stupid Dream'', slightly withdrew from the spacy, psychedelic, EpicRocking material on their earlier albums, adding elements of AlternativeRock and accentuating their ProgressiveRock influences. Starting with ''In Absentia'', their albums have started getting heavier and veering into progressive metal territory, although not to the extent of such bands as {{Opeth}} or Music/DreamTheater.

Steven Wilson is known to be close friends with [[{{Opeth}} Mikael Akerfeldt]], and the two have collaborated with each other's bands - Wilson sang backing vocals on and produced four Opeth albums (''Blackwater Park'', ''Deliverance'', ''Damnation'', and the upcoming ''Heritage'') while Akerfeldt contributed backing vocals to three songs on ''Deadwing'' and a guitar solo to "Arriving Somewhere But Not Here". The two have even collaborated on a project entitled 'Storm Corrosion'.

Porcupine Tree's members are:
* Steven Wilson (guitar, vocals, keyboards, [[IAmTheBand bass and drums/drum machine on the first few albums as well]], various other instruments)
* Richard Barbieri (keyboards/synth since 1993, formerly a member of Music/{{Japan}})
* Colin Edwin (bass guitar since 1993)
* Gavin Harrison (drums since 2002)
* John Wesley (guitar, vocals since 2002, touring member only)

Former members and noteworthy guest appearances:
* Chris Maitland - drums (1993-2002)
* [[{{Opeth}} Mikael Akerfeldt]] - guitar, backing vocals on Deadwing (Opeth member)
* Adrian Belew - guitar on Deadwing (KingCrimson member)
* Alex Lifeson - guitar solo on "Anesthetize" ({{Rush}} member)
* Robert Fripp - soundscapes on "Way Out Of Here" and guitar on "Nil Recurring" (KingCrimson member)
* Suzanne Barbieri - vocals on "Up the Downstair" and "The Sky Moves Sideways Phase 2" (Richard's wife, one of the few other vocalists on a PT album besides Wilson)

Porcupine Tree's discography is a bit knotty. Their main albums are as follows:
* ''On the Sunday of Life'' (1991) - consists of tracks from the early cassettes ''Tarquin's Seaweed Farm'', ''Love, Death & Mussolini'' and ''The Nostalgia Factory''. Wilson mentioned in the reissue's liner notes that this album is impossible to remaster because it was recorded directly to tape on various 4-, 8- and 16-track machines at his home, and the tracks would be wiped once he finished a song.
** ''Yellow Hedgerow Dreamscape'' (1992) - a compilation of the leftover early tracks that didn't make it on ''Sunday''. Includes the original cassette version of "Radioactive Toy", a song that was re-recorded for ''Sunday''. The CD version includes a cover of "The Cross" by {{Prince}}, while the vinyl version replaces that with "Out" (originally from ''Love, Death & Mussolini'').
* ''Up the Downstair'' (1993) - features {{Early Bird Cameo}}s from Barbieri and Edwin; PT only became a functioning band after the album was released.
** Remastered, partially re-recorded with the band and re-released in 2005, bundled with the ''Staircase Infinities'' EP.
* ''The Sky Moves Sideways'' (1995) - ''almost'' their first band effort; time constraints during recording meant that "The Moon Touches Your Shoulder" and "Dislocated Day" were entirely recorded by Wilson alone.
** Similarly remastered, re-recorded with Harrison's drums and re-released in 2003. None of the three editions (UK, USA, remaster) have the same tracklist, or the same version of "Moonloop".
* ''Signify'' (1997) - their first full-band effort.
** Remastered and re-released in 2003, bundled with the demos / outtakes disc ''Insignificance''.
* ''Stupid Dream'' (1999) - the album where they started moving away from psychedelia towards prog-rock.
** Remastered in 5.1 surround sound for DVD-A in 2006.
* ''Lightbulb Sun'' (2000)
** Remastered in 5.1 surround sound for DVD-A in 2008.
* ''In Absentia'' (2002) - the start of their move towards ProgressiveMetal
* ''Deadwing'' (2005)
* ''Fear of a Blank Planet'' (2007)
* ''The Incident'' (2009)

Plus the predictable [[http://en.wikipedia.org/wiki/Porcupine_Tree_discography bunch of EPs, compilations, rarities and live albums]].

!!PorcupineTree provides examples of:
* AllStarCast: Steve Wilson works with a lot of famous prog and metal musicians, and they often end up performing on Porcupine Tree albums. [[{{Opeth}} Mikael Akerfeldt]] and Adrian Belew from KingCrimson show up on ''Deadwing'', and [[{{Rush}} Alex Lifeson]] and [[{{KingCrimson}} Robert Fripp]] both contribute to ''Fear of a Blank Planet''. There's also plans for a {{Supergroup}} featuring Mikael, Steven, and [[Music/DreamTheater Mike Portnoy]], though that seems to be stuck in DevelopmentHell.
** There's hope for the Portnoy/Wilson/Akerfeldt project now that Portnoy's left Dream Theater though.
*** {{Jossed}}; according to Akerfeldt Portnoy is probably not going to be involved.
* BlasphemousBoast[=/=]BiggerThanJesus: "Slave Called Shiver":
-->I may be nothing now, but I will rise\\
I'll have more followers than Jesus Christ
* {{Breather Episode}}: "Sentimental", which is stuck between [[{{Epic Rocking}} "Anesthetize"]] and "Way Out of Here", two of their bleaker songs.
* CerebusSyndrome: Seen most from ''In Absentia'' onwards - while there were always darker themes present here and there in their music ("Radioactive Toy", much of ''Signify''), the earlier music was usually lighter, more whimsical and psychedelic, even when the lyrics were dark (compare the lyrics of "Radioactive Toy" to the almost {{Pink Floyd}}ian arrangement). As time's gone on, both the music and the lyrics have become dark and pessimistic. For a good example, compare "Nine Cats" to "Fear of a Blank Planet". Same could be said about No-Man. Steven Wilsons band together with Tim Bowness. Compare "You Grow More Beautiful" to "Mixtaped"
* {{Concept Album}}: Almost all their albums have uniting themes, although they aren't always concept albums in the strictest sense.
** ''Signify'' is about the ways that people try to feel that their lives matter.
** ''Lightbulb Sun'' is concerned largely with relationships that are broken, ending or haunting people after they end.
** ''In Absentia'': Loosely tells the story of a serial killer
** ''Deadwing'': While not necessarily one, it does link together elements of a movie script Steven was writing.
** ''Fear of a Blank Planet'': Told from the viewpoint of a teenager in modern day society, isolated and alienated by prescription drugs and mass media. According to that other [[http://en.wikipedia.org/wiki/Fear_of_a_Blank_Planet#Concept wiki]] it was heavily influenced by [[http://en.wikipedia.org/wiki/Lunar_Park Lunar Park]].
** ''The Incident'': Has a theme of moments that change someone's life forever. The title track was inspired by a car accident Wilson witnessed, and his thoughts the the word "incident" was a very cold way to describe an event that could destroy people's lives. Another song (The Blind House) was inspired by the US government raid on a cult's ranch in Texas where polygamous marriages to teenage girls were going on.
* CoverVersion: The US version of ''Yellow Hedgerow Dreamscape'' includes a cover of {{Prince}}'s "The Cross", and ''Signify'' includes a cover of [[Music/{{Neu}} Neu!'s]] "Hallogallo".
* DoesNotLikeShoes: Steven Wilson usually goes barefoot.
* DownerEnding: In a musical sense, every one of their albums from ''Stupid Dream'' onward. Also, if you view ''In Absentia'' as a story, it has this in a narrative sense no matter how you interpret the story.
** Even more so with ''Fear of a Blank Planet'', in which the protagonist is [[spoiler: DrivenToSuicide]].
* {{Epic Rocking}}: Oh god, where do we start. In the lengthy but not all too crazy category, Dark Matter, Deadwing, Burning Sky, Up the Downstair, Don't Hate Me, Arriving Somewhere But Not Here, Hatesong, and Radioactive Toy, to name a few in the 8-12 minute range. Anesthetize, Russia On Ice, each half of The Sky Moves Sideways, the full version of Even Less, and the album version of Moonloop are all around 14-17 minutes (with the unedited version being 40 minutes- the max of 2 sides of vinyl.) The full version of The Sky Moves Sideways is around half an hour long, the album "The Incident" is a 55-minute "song cycle" (alongside a second 20-minute disc), and Voyage 34 is '''70 MINUTES LONG.'''
* TheFourChordsOfPop: Discussed in "Four Chords That Made A Million".
* FunWithAcronyms: "Linton Samuel Dawson"
* LastOfHisKind: "A Smart Kid":
-->A spaceship from another star\\
They ask me where all the people are\\
What can I tell them?\\
I tell them I'm the only one\\
There was a war but I must have won
* LoudnessWar: Steven is opposed to this, including a disclaimer in the inner sleeve of ''Deadwing'' that the album is mastered less loud to maintain dynamics.
** The CD versions are still fairly compressed, though, most likely due to ExecutiveMeddling. There is audible clipping on the CD versions of ''In Absentia'' and especially ''Deadwing,'' but the mastering on later [=CDs=] is less crude. This is largely averted on the DVD-audio 5.1-channel mixes however, except ''In Absentia'', which, for some reason, is still clipped. (There is still some compression on some channels of the other 5.1 mixes, but not all, and it is not as bad as on the CD versions).
* MohsScaleOfRockAndMetalHardness: Getting harder over their career, from 4/5 at the beginning to a pretty solid 6 for most of ''In Absentia'' and ''Deadwing'' to 6 or 7 on ''Fear of a Blank Planet'' and ''The Incident''.
* NeoclassicalPunkZydecoRockabilly: "Trains" has a random banjo interlude in the middle, and "Anesthetize", which starts off sounding vaguely like {{Radiohead}}, progresses on to a metal section, and ends with a psychedelic sounding movement that has massive vocal overdubs.
* NewTechnologyIsEvil: Steven Wilson dislikes [[{{MP3}} MP3s]] and [=MP3=] players, for decreasing the quality of music and the significance of it, respectively. He takes a few shots at iPods and video games on ''Fear of a Blank Planet''.
** In his film Insurgentes, he shows this by actually destroying iPods [[http://www.youtube.com/watch?v=06JWDLTx4l0 in]] [[http://www.youtube.com/watch?v=ydaFKXrRjj8 a]] [[http://www.youtube.com/watch?v=sad-xhIZgz8 number]] [[http://www.youtube.com/watch?v=fMsffbe87lY of]] [[http://www.youtube.com/watch?v=tUjl0dXfr5s different]] [[http://www.youtube.com/watch?v=oIQr7HMOF-s ways.]]
* OlderThanTheyLook: Steven, definitely. [[http://www.google.com/imgres?q=steven+wilson&um=1&hl=en&safe=active&client=safari&sa=N&rls=en&biw=1066&bih=616&tbm=isch&tbnid=H53v3tgPmYqwxM:&imgrefurl=http://www.orphaned-disciples.org/site/lang/en/2009/11/30/steven-wilson-comments-on-mixing-the-new-orphaned-land-album/&docid=xrUP948tai4tQM&imgurl=http://www.orphaned-disciples.org/site/wp-content/uploads/StevenWilson.jpg&w=534&h=800&ei=8lyqT5WqOob22gWX4qGmAg&zoom=1&iact=hc&vpx=806&vpy=215&dur=2479&hovh=275&hovw=183&tx=94&ty=199&sig=105116874912750534258&page=1&tbnh=130&tbnw=87&start=0&ndsp=20&ved=1t:429,r:12,s:0,i:99 Take a nice long look at this picture.]] He's 44.
* ThePeteBest: A lot of the lyrics on ''Sunday'' were written by one of Wilson's school friends, Alan Duffy. By the time the band became an actual concern, the two had lost contact.
* PrecisionFStrike: There's a particularly effective one in the extended cut of ''Even Less.'' There's another one on "The Incident".
* ProgressiveMetal: ''In Absentia'' onward. It helps that ever since that album, the metal community has considered them a member, with websites such as ''Metal Storm'' and ''Metal Underground'' reviewing their latest albums and adding their artist profile to their database.
* RecordProducer: Steven Wilson does it himself, and has produced other bands (most notably {{Opeth}}). He's also been remixing {{King Crimson}}'s old albums for re-release. Other bands he's remixed include {{Caravan}}, JethroTull and EmersonLakeAndPalmer.
* SelfBackingVocalist: Wilson, most of the time.
* StoicSpectacles Steven Wilson is a pretty man. More so with glasses than without.
* ShoutOut: "Pure Narcotic" has one in the first verse, to the {{Radiohead}} album "The Bends". A slightly less subtle one would be The Sky Moves Sideways, a psychedelic rock album with five tracks, the first and last of which are halves of the titular song. Does this remind any Pink Floyd fans of anything? And ''The Incident'' contains the song "Time Flies", which is about nostalgia and contains MANY musical and lyrical hat-tips to Pink Floyd - ''Animals'' was the first album Steven Wilson bought as a child. It also has passing references to Music/TheBeatles and JimiHendrix.
** ''Fear of a Blank Planet'' is named after PublicEnemy's ''Fear of a Black Planet''.
* TakeThat: A bunch to the music industry, such as "Piano Lessons" and "The Sound of Muzak". The entire ''Fear of a Blank Planet'' album can be seen as one to today's youth popular culture as a whole, with "Anesthetize" directly mentioning MTV.
** Being as how ''Fear of a Blank Planet'' is told from the perspective of the son of ''[[BretEastonEllis Lunar Park]]''[='=]s middle-aged protagonist, it's debatable whether Steven Wilson is more disgusted with the adult producers or the young consumers.
** The title of "The Nostalgia Factory" is a swipe at the music press' short attention span (and hilariously, ''Melody Maker'' compared the song to {{Ride}} when it came out, proving the point).
-->'''Wilson''': One thing Iíve tended to experience with the British music press is that if you try to talk to them about the history of music, their knowledge often doesnít go back beyond TheStoneRoses or Happy Mondays.
* UncommonTime: As PT are a ProgressiveRock band, this is pretty much obligatory. Large portions of "Strip the Soul" are in 5/4, for example, while "The Start of Something Beautiful" mostly switches between 9/8 and 5/4.
* {{Word Salad Lyrics}}: Mostly seen on the earlier work, like "Nine Cats".
** Attributable, to an extent, to the fact that much earlier work featured lyrics which were gifted to Wilson by his friend Alan Duffy, along with the much more psychedelic direction of earlier albums.
