Karl Alvarez's new band Underminer, which features drummer Jonny Freedom, bassist Dave Bush and guitarist Jeff Reese, has put several new live recordings online via MySpace.

The band will perform at an upcoming benefit for Alvarez (that's right, he's playing his own benefit) on September 29th. The All / Descendents, veteran recently suffered a heart attack and will use the money raised to help offset the medical bills. The event takes place at the Aggie Theatre in the band's hometown of Fort Collins, CO.
