Atheist is a death metal band from Florida, founded in 1984 by the vocalist and guitarist Kelly Shaefer, guitarist Rand Burkey, bassist Roger Patterson and drummer Steve Flynn. The band is known for its highly technical playing style and its 1991 album, Unquestionable Presence, is regarded as an important landmark of the technical death metal genre. After disbanding in 1994, the band reformed in 2006 and has since released one studio album and a live DVD.
