Dr. Dog have always borrowed liberally from the past, but for their new album they turned to their own decade-plus history to find inspiration. The Psychedelic Swamp, the Philly band’s ninth record, is drawn from songs written by Scott McMicken and Toby Leaman in 2001, before they had officially formed as a band. Psychedelic Swamp lives up to its title, delivering muggy and mucky songs that descend into jam band territory at times. Listen via NPR below.
