Taken from Encyclopaedia Metallum:

Obituary were originally formed in 1984 under the name Executioner. Since there was already a band called Executioner in Boston they changed to Xecutioner and then finally to Obituary in 1988 after they signed with Roadrunner Records.

Obituary are considered to be one of the pioneering bands of the death metal genre. They started playing music in the vein of Venom and Celtic Frost. Once the band started hearing groups like Possessed, they realized that they want to make music as "sick as these guys."

Obituary's "The End Complete" is crowned the best selling pure death metal album ever released, selling over 100,000 copies in the US, and over a quarter million worldwide. Also, the new Obituary logo (as can be seen on "The End Complete") has been considered Roadrunner's best selling shirt print in it's history.

Obituary had a six year absence between 1997-2003 because the band members had other priorities to turn to like raising new families and getting "real jobs". The reunion is credited to Donald Tardy's time playing in Andrew W.K.'s band - during one live performance in Florida, some of the other Obituary members were present and decided to play some Obituary tunes just for fun for the audience, eventually leading to a full-time reunion.

Trevor Peres and John Tardy have collaborated with the Brooklyn-based rapper Necro on his album The Prefix For Death. The band members know Necro through his days as a bass player for death metal band Injustice (USA).

John Tardy said in a interview that there is no message in Obituary's lyrics, just some randoms words and statements about death and the rest is just growling.

Allen West was sent to prison in 2007. John Tardy later revealed in interview that West had been jailed for repeated drink driving offenses. Ralph Santolla, shortly after departing Deicide, replaced him for "Xecutioner's Return".

For the 2010 South American tour, Obituary's long time friend and Floridian death metal stalwart Terry Butler (Death, Massacre, Six Feet Under (USA), Denial Fiend, Obliterhate) took on bass duties in place of Frank Watkins.
