The band is currently composed of founding vocalist Chris Barnes, bassist Jeff Hughell, drummer Marco Pitruzzella, and guitarists Ray Suhy and Jack Owen.

A dual studio/live EP, it contains three studio recordings ("Insect", "Drowning", and a Judas Priest cover, "Grinder") and four tracks from Haunted performed live.

Combined with Barnes' departure from Cannibal Corpse, the arrival of Swanson helped turn Six Feet Under from a mere side-project to a band in its own right.

During the summer of 2000, Six Feet Under participated in the Vans Warped Tour, a festival that, at the time, usually featured punk rock bands.

[5] Six Feet Under undertook a lengthy bout of American tours, commencing in the summer of 2002, with supporters Skinless and Sworn Enemy.

AllMusic reviewer Wade Kergan remarked that the death metal-makeover on these forefather songs "are equal parts menace and kitsch... Six Feet Under are obviously having a blast as they rip through them.

While writing the lyrics, Chris Barnes reportedly entered "a vision" from smoking large quantities of marijuana and meditating.

In November 2005, Chris Barnes joined the Finnish death metal band Torture Killer as lead vocalist for a side project.

According to music critic Chad Bowar, the album has "catchy death metal songs... [that are] crushingly heavy, but also have a great groove to them.

As announced on January 31, 2008, Chris Barnes officially parted ways with Torture Killer, to be replaced by Juri Sallinen.

Drummer Greg Gall was currently writing and recording material with a new band called Exitsect, along with guitarist Sam Williams (Denial Fiend, Down by Law), bassist Frank Watkins (Obituary, Gorgoroth), guitarist Joe Kiser (Murder-Suicide Pact, Slap Of Reality) and vocalist Paul Pavlovich (Assück).

In November 2011, Rob Arnold and Matt Devries posted statements saying they have departed from Chimaira to play in Six Feet Under full-time.

However, in 2012, Matt Devries left the band to join Fear Factory, replacing longtime bassist Byron Stroud.

It was also announced on the same day that Rob Arnold would be replaced by Swedish guitarist Ola Englund of bands Feared and Scarpoint.

In April 2015, Jeff Hughell left the Hatefest tour in Europe and Victor Brandt of Entombed filled in as a temporary bassist.

[17] The band released a digital-only EP on July 6, 2018, titled Unburied, consisting of previously unreleased material from the recording sessions of their prior four albums.
