There are at least four groups called Six Feet Under (+ two '6 Feet Under')

1) Six Feet Under (USA) is a death metal band with heavy rock influences on some of their albums. Originally a side project for Cannibal Corpse vocalist Chris Barnes and former Obituary guitarist Allen West, Six Feet Under eventually became a full-time proposition when friction between Barnes and his other bandmates became too much to bear.

The Day Everything Became Nothing is a Goregrind band from Melbourne, Australia. Formed in Melbourne in 2002, The Day Everything Became Nothing continues to deliver extreme percussive grind that is characterised by its dirty, muddy sound. The band's name is derived from the EP of the same name by Canadian punk rock band NoMeansNo. The remarkably guttural vocals, by aid of a pitch-shifting Whammy pedal, are done by Tony Forde, of Blood Duster notoriety, but the band originally featured Kody Abrams.

There are two bands with the name Bonestorm 1) Bonestorm was a Minneapolis, MN metalcore/comedic-metal band that consisted of future members of Everest/Iron Thrones and Nehemiah. Vocals on their first and only album, entitled "Robots Are So Tough Because They Don't Have Any Feelings, That's Why They Conquered The Dinosaurs?", were performed by Bill Kurth of End This Day, although he never played a show with the band and was never listed as an official member.
