Staind is an American rock band formed in Springfield, Massachusetts. They consist of Aaron Lewis on vocals, Mike Mushok on guitar, Johnny April on bass, and (formerly) Jon Wysocki on drums.

They have changed up their genres since their first album. They started with a raw heavy-metal/nu-metal sound (''Dysfunction''), then did ''Break the Cycle'', which received a lot of fame; their hit single "It's Been Awhile" has received a lot of radio play, and ranked high on many charts.

Staind started off making songs about depression, hate, and drug habits on their debut album, ''Tormented''. Their next album, ''Dysfunction'', remains softer and less aggressive. It still revolves around the topics of dysfunction and anger. They then released their most popular album, ''Break the Cycle'', which adopts a softer sound than their last album, containing ballads and slower less aggressive tracks. This pattern continues up to their newest self titled album, which returns to their roots, and brings back a heavy sound.

Since their last album, they changed up their drummers. Their new drummer is Sal Giancarelli as of 2011. Since 2011, Lewis has also released two albums of CountryMusic.

!!Staind has examples of the following tropes:

* AlternativeRock
* AsTheGoodBookSays: After "Four Walls", there is a hidden track featuring a priest reciting Bible verses.
* BaldOfAwesome: Aaron Lewis.
* ConceptAlbum: ''Tormented'' [[spoiler: is based around a depressed person who cocks a gun at the beginning of the first song of the album ("Tolerate"), and shoots himself at the end of the last song ("Four Walls").]]
* CoverVersion[=/=]FirstAndForemost: The chords for "So Far Away" have been used in a Music/RascalFlatts song, "What Hurts the Most". Ironically, Aaron Lewis covered that song.
* DeathSong[=/=]DrivenToSuicide: [[spoiler: "Four Walls".]]
* DirtyBusiness: "Can't Believe".
* DysfunctionJunction: ''Dysfunction'' has a '''lot''' of songs about this subject.
* GenreShift: They've done this ''a lot''. ''Tormented'' was full-on metal, ''Break the Cycle'' was slower and softer, ''The Illusion of Progress'' was mostly acoustic, and on their self-titled seventh album, they went back to metal.
* HeroicBSOD: Much of "Reality".
* HiddenTrack: ''Tormented'' and ''Dysfunction'' both have this.
* {{Improv}}: Half of "Outside" was made up on the spot, thanks to [[Music/LimpBizkit Fred Durst]].
* LongRunnerLineUp: A Type 1 before Wysocki left.
* LoopedLyrics: The end of "Self Destruct" has these:
--> ''I self destruct my mind''
--> ''I self destruct my world''
--> ''I self destruct my life.''
* LoudnessWar: ''Break the Cycle'' is actually the victim of it.
* MohsScaleOfRockAndMetalHardness: The band was jumping up and down the scale pretty much during its career. ''Tormented'' is a hard 8-9 and hits 10 at some parts due to production, although the closer "Four Walls" is [[Main/SurprisinglyGentleSong about 3]]. ''Dysfunction'' goes around 7-9 due to acoustic parts of "Home", while the sound of distorted guitars is as crushing as it was on "Tormented". ''Break the Cycle'' drops to 6-8 range with "Epiphany" dropping to 2. Both ''14 Shades of Grey'' and ''Chapter V'' are mostly around 4-6 with acoustic songs dropping to 2, ''Illusion of Progress'' is limited to 5. The self-titled album brings the band back to 7-9 range, except of "Something to Remind You" which is 1.
* NonAppearingTitle: "Spleen", "Change", and many others.
* {{Rockumentary}}: ''The Making of Staind''.
* SanitySlippageSong: "Self Destruct" is this.
* SelfDeprecation: Their first three albums had a lot of this.
* SelfTitledAlbum
* SurprisinglyGentleSong: "Four Walls", "Epiphany" and "Something to Remind You" are the only soft songs on their albums.
* WhenImGoneSong: "Something to Remind You".
* XtremeKoolLetterz: Used in their lyrics sheet for ''Tormented''.
