Helmet is an extremely influential NoiseRock / PostHardcore band from New York City formed in 1989. They consisted of [[FaceOfTheBand Page]] [[IAmTheBand Hamilton]] on lead guitar and vocals, Henry Bogdan on bass, Peter Mengede on Rhythm Guitar and John Stanier on drums. They broke up in 1998 but have reformed in 2004, with a new lineup, and released two albums ''Monochrome'' in 2006 and ''Seeing Eye Dog'' in 2010.

* AlternativeMetal: TropeCodifier.
* BreakupBreakout: John's [[Music/{{Battles}} second band]] was far more successful than Helmet.
* CoverVersion: Music/BlackSabbath's "Symptom Of The Universe", Music/KillingJoke's "Primitive", Music/LedZeppelin's "Custard Pie" (with guest vocals by [[Music/TheJesusLizard David Yow]]). Perhaps a bit more surprising are versions of Music/TheBeatles "And Your Bird Can Sing" and "Beautiful Love", a jazz standard originated by the Wayne King Orchestra (which isn't THAT surprising when you consider that Page Hamilton originally went to New York City to study jazz guitar before he fell in with Glenn Branca's orchestra).
** They also contributed a cover of the ''Anime/{{Gigantor}}'' theme to the compilation ''[[https://en.wikipedia.org/wiki/Saturday_Morning:_Cartoons_Greatest_Hits Saturday Morning: Cartoons' Greatest Hits]]'', and a cover of Music/{{Bjork}}'s "Army of Me" to the first ''[[https://en.wikipedia.org/wiki/Music_for_Our_Mother_Ocean Music for Our Mother Ocean]]''.
* IAmTheBand: Page Hamilton wrote all the songs back when they started, and now he's the only original member left. A sign of this is the fact that the song "Throwing Punches" first appeared on the soundtrack album to ''{{Film/Underworld}}'' credited as a Page Hamilton solo work, but then the same version of the song appeared on Helmet's album ''Size Matters'' a year later.
* MohsScaleOfRockAndMetalHardness: Anywhere from 6 (Milquetoast) to 9 (Repetition)
* NoiseRock: Much more [[HeavyMetal heavy]] though.
* PostHardcore: Particularly their early material.
* RapRock / RapMetal: "Just Another Victim", their collaboration with Music/HouseOfPain. In live performances, they tended to slightly RearrangeTheSong by skipping the extended rap section entirely.
* UrExample[=/=]UnbuiltTrope: For NuMetal, while their use of drop d tuning has influenced acts such as Music/{{Deftones}}, Music/LimpBizkit, and Music/{{Korn}}, they have denied it and said that the true UrExample is Music/FaithNoMore. Also UrExample of Post Metal with songs such as Sinatra and Milquetoast which featured repetitive, atmospheric sections building up to massive climaxes
