In the last few years, the increased popularity of djent has seen them gain a lot of attention due to their undeniable influence on a lot of recent bands, as well as other progressive bands such as Music/ProtestTheHero, who have stated they are their biggest influence.

!!Tropes that apply to [=SikTh=]:
* AlbumTitleDrop:
** "Part of the Friction".
--> "Try to make them challenge you. Lights are falling, Death of a day, deader than day. Victory? Victory? Victory? '''Death of a dead day'''."
** "Wait For Something Wild".
** "Golden Cufflinks"
--> "but a '''future in whose eyes?'''"
* AlternativeMetal: More prominent in their post-hiatus work.
* AnimatedMusicVideo: "How May I Help You?".
* AscendedFanboy: On the poster for Download Festival 2014's line-up, they were placed next to Down: they are huge fans of Phil Anselmo's work.
* TheBandMinusTheFace: Mikee and Justin both left the band. Unable to find new vocalists, they split up soon afterward.
* BasedOnATrueStory:
** There is a long standing fan theory that "Hold My Finger" is somewhat autobiographical.
** "Philistine Philosophies" is about Mikee's struggles with trying to adapt to the current day music industry. The line "so hop on the wagon or be a mystical tree" was inspired by a conversation he had with his manager where he was told that he needed to have a social media presence or he would be left behind.
** "Golden Cufflinks" is about the gentrification of Central London and the damage it's caused to the cultural life of the city. The song's lyrics reference the redevelopment of Tin Pan Alley and the music video shows news clippings about old London venues such as The Mean Fiddler closing down.
* CallBack: "Golden Cufflinks" has the line "yet another bland street bloom", referring back to the track of that name from Death Of A Dead Day.
* CoolPlane: Sort of. Mikee owns a flying camera which is able to fly at up to 1000 feet into the air. Why? [[RuleOfCool Because it's cool, of course!]]
* CoverVersion: Of Music/NickCave's "Tupelo". Despite being about as far from technical metal as you can get, they hardly changed anything. And it ''works''.
* EpicRocking: Mostly averted. Despite their highly experimental nature, they only have two songs over 7 minutes.
* GaiasVengeance: The video for "Bland Street Bloom".
* LargeHam: The vocals and lyrics in general, even more so on material from the first album.
* LonelyPianoPiece: Both parts of "Emersion".
* LonersAreFreaks: Rod is portrayed this way by everyone he meets in "How May I Help You?". [[spoiler:Even by his girlfriend Miranda, when he finds out what her job ''really'' is]].
* LyricalDissonance: A lot of their songs are fast, furious, and very noisy metal with lyrics that are entirely surreal or just stupid. Averted somewhat in recent years.
* {{Metalcore}}: Often get labeled as this, but it's mostly just the singing.
* ManOfAThousandVoices: Mikee Goodman's vocal style can range from anywhere between death growls and high shrieks to mounrful melodic tones reminiscent of JimMorrison, NickCave or LeonardCohen, and even imitate various different accents.
** He explores this to its biggest extreme yet on ''The Future in Whose Eyes''. For some parts of "Cracks of Light" he performs the vocals in a cockney accent and "The Moon's Been Gone For Hours" is performed in an Australian accent.
* MetalScream: Plenty of screaming all over the place, some of it downright psychotic.
* MohsScaleOfRockAndMetalHardness: Usually around a solid 9, but they drop to about a 5 or 6 on softer songs, and max out at the 10-11 range in their harder material.
* MrExposition: The bartender in "How May I Help You?". [[spoiler:He reveals that Miranda is a prostitute]].
* NuMetal[=/=]AvantGardeMetal: Frequently associated with the genre, though they are among the most respected.
* OncePerEpisode: Mikee's spoken word poems.
* ToiletHumour: Rod's revenge method in "How May I Help You".[[spoiler:He puts laxatives into their tea]].
* ProgressiveMetal: Often crossing over into straight-up experimental.
* RedOniBlueOni:
** TheLeader: Mikee and Pin.
** TheLancer: Justin/Joe and Dan.
* SingingSimlish
* SopranoAndGravel: Male example and Mikee and Justin/Joe can play either role.
* SurprisinglyGentleSong: They have a few more melodic songs, but each release has a distinct one: the poppy "Peep Show" from the first album the atmospheric "In This Light" from the second and "Days Are Dreamed" from the Opacities EP.
* SubduedSection: They like this a lot.
* VocalTagTeam: Mikee and Justin are one of the best and possibly most influential examples of this.
* XMeetsY: Best described as Music/{{Korn}} meets Music/TheDillingerEscapePlan meets Music/{{Meshuggah}} meets Music/{{Atheist}}.
