Head For The Hills has become one of the biggest names in Colorado bluegrass since forming in 2003. The Fort Collins quartet in May released its fourth album, "Potions And Poisons." It features songs about addiction and heartache, but with upbeat folk and country energy. Head For The Hills last month stopped into the CPR Performance Studio to play three songs from the new album. Stream that performance and check out bassist Matt Loewen and fiddle player Joe Lessard's interview with CPR News for more on the new album.
