Palm released its sophomore album, "Rock Island," earlier this year. The Philadelphia quartet's music is hard to pin down: It incorporates elements of rock, pop, tropicalia, electronica and other genres for a bizarre and exciting sound. The band recorded much of the album in a secluded farmhouse in New York state. The band members brought their eccentric sound into the CPR Performance Studio before a show at Lost Lake in Denver. They played three songs from "Rock Island" and spoke with Jeremy Petersen about constantly reinventing their sound, their experimental music influences and whether or not rock music is "dead."
