Volcano was released in 2004. The album was released as a limited edition on Skunk Records and was not reprinted until 2025 when it received a limited vinyl and CD release from Don Giovanni Records.

Trouser Press, which gave the eponymous album by Eyes Adrift a favorable review, said that Volcano was even better. They noted the "simple rough-in-the-studio mix", the reggae feel of Poutney's basslines, and the "high lonesome" feeling conjured by Kirkwood's "unfettered vocals". They wrote:

"Twisted Seeds" is a high point in Kirkwood's career – with its Jerry Garcia influence and overlapping verses, it's nothing you'd find on a Meat Puppets album. "Arrow" features pseudo-pedal steel and Latin guitar with stylings that echo the era of Meat Puppets II.

Punknews.org said that the reggae- and country-influenced songs were some of the best, and called the album "one of the best of the post-Sublime era" and a "truly unique collaboration and a solid collection of songs".

All songs by Curt Kirkwood.
