Glassjaw is a {{Post-Hardcore}} band from Long Island, New York. The band was founded in 1992 and has released two albums so far: Everything You Ever Wanted To Know About Silence (hereby abbreviated as EYEWTKAS - released in 2000) and Worship And Tribute (2002), both regarded as classics within their genre. They are know for putting on chaotic live shows and for their frequent lineup changes.

!Current members:

* Daryl Palumbo- lead vocals
* Justin Beck- guitars
* Manuel Carrero- bass
* Durijah Lang- drums

!Tropes:

* AccentUponTheWrongSyllable: Any time Daryl uses clean vocals.
* BreakupSong: Most of EYEWTKAS is made up of these. Definitely not the resigned "I wish you the best" kind, either.
* CarefulWithThatAxe
* ClusterFBomb: They probably use "whore" on EYEWTKAS even more than they use the f-bomb.
* DigitalPiracyIsEvil: Averted. The band encourage fans to steal EYEWTKAS off the internet rather than give money to Roadrunner Records by purchasing it. This is due to an ugly spat between the band and Roadrunner after the recording of their first album.
* HighTurnoverRate
* IllBoy: Daryl suffers from Crohn's Disease and has had to cancel concerts because of it.
* IndecipherableLyrics: Daryl's unconventional singing style, combined with loud guitars and frequent screaming make most of their lyrics hard to understand. Not that the general [[WordSaladLyrics Word Salad]] helps any.
* KickTheDog: Roadrunner allegedly forced Daryl to continue touring, even after the stress of performing caused him to have potentially-fatal relapses of Crohn's Disease.
* TheLancer: Justin Beck, the only remaining original member other than Daryl.
* MetalScream: Usually a type 2 or 3.
* MisogynySong: "Lovebites and Razorlines", "Hurting and Shoving (She Should Have Let Me Sleep)"... most of them, being about girls who've hurt Daryl.
* MohsScaleOfRockAndMetalHardness: A 8/9 on their first album, about a 7 on Worship and Tribute and a 5-7 for the last few [=EP=]s. Then there are songs like "Siberian Kiss", which goes from a 9 to a 4 and back again twice over the course of the song.
* NeoclassicalPunkZydecoRockabilly: Worship And Tribute mixes their usual {{Post-Hardcore}} / AlternativeMetal sound with elements of NoiseRock, FunkRock, {{Jazz}}, Pyschedelic Rock, ThrashMetal, and Afrobeat.
* NewSoundAlbum: Worship and Tribue, which had a more experimental and somewhat lighter sound.
* ThePeteBest: Pretty much anyone who played with the band prior to the recording of their first album.
* ScaryMusicianHarmlessMusic: {{Inverted}}. They don't look intimidating at all, but their music is highly aggressive and brutal.
* SurprisinglyGentleSong: The HiddenTrack on EYEWTKAS. Also, "The Number No Good Things Can Come Of", a piano and drums piece and the lounge-style "Oxycodone", both off of the El Mark EP. Most of the Coloring Book EP also counts.
* TakeThat: Most of EYEWTKAS is a vicious screed against one or more of Daryl's ex-girlfriends.
* WhatCouldHaveBeen: "Convectuoso" was supposed to be the last track on Worship and Tribute, but did not make it [[ExecutiveMeddling due to Roadrunner Records holding the rights]].
* WordSaladLyrics: Most of the lyrics on Worship And Tribute are very ambiguous. In stark contrast to the previous album... Recent material, such as the Coloring Book EP has continued in this style.
* YourCheatingHeart: "Siberian Kiss": "Give me back my pictures of me/Me and you and him makes three.
