Caldera is a live album by the Sam Rivers Trio, led by multi-instrumentalist and composer Rivers, and featuring double bassist and bass clarinetist Doug Mathews and drummer and saxophonist Anthony Cole. It was recorded on March 9, 2002, at the Freeport-McMoRan Theatre, Contemporary Arts Center in New Orleans, Louisiana, and was released in 2022 by NoBusiness Records as volume 6 of the Sam Rivers Archive Series. The Rivers Trio with this lineup also appeared on Concept, Firestorm, and Celebration. Caldera is based on material selected from Rivers' massive recorded archives, which are curated by writer and producer Ed Hazell, who spent a year reviewing tapes with the goal of choosing the best recordings for release by NoBusiness Records.
