Atheist and Origin

Atheist, formed in 1984 in Florida, pioneered progressive death-jazz metal. Known for complex albums like "Piece of Time" and "Unquestionable Presence," they faced adversity but gained lasting respect. Despite limited commercial success, they toured globally and collaborated with Cynic bassist Tony Choy. The tragic death of bassist Roger Patterson marked their journey. They disbanded after releasing "Elements" in 1993.

Origin, hailing from Topeka, Kansas, is a technical death metal band known for fast, punishing tracks. Formed in 1997, their acclaimed albums include "Antithesis" and "Unparalleled Universe". Guitarist Paul Ryan remains an original member. Key collaborations are with Cryptopsy and Dying Fetus. Vocalist Jason Keyser joined in 2011. Their 2022 album "Chaosmos" marked their return to the studio.
