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.

there are 5 acts using the name DEAD: #1: DEAD was founded in early May 1990 by Uwe (b/v), Dany (g/v) & Peter (d/v). Main target at that time was playing Gore/Grind/Death in its rawest form ala good old (!) Carcass, Pungent Stench, etc. But lyrically it was totally replaced after the release of the 2nd 7”ep “Slaves to abysmal perversity” by the nowadays well-known dirty humour.. DEAD split up on 22nd May 1998 - on their last gig at the “FTC II” – Festival.
