After 12 years of expanding the definition of rock music, Tortoise will release a highly anticipated box set. Lazarus Taxon is the paleontological term for a species that disappears, then reappears in the fossil record; its namesake is this collection including rare singles from foreign releases and tour EPs, compilation tracks, previously unreleased material and the out-of-print 1995 album Rhythms, Resolutions & Clusters. The set contains three CDs and one DVD, which features most of Tortoise’s music videos and extensive and rare live performance footage.
