The Expanders may play vintage reggae, but they're more than revivalists. The SoCal-based band champions '70s/'80s roots, focusing on 3-part harmonies and songwriting. John Asher (drums, vox), John Butcher (guitar, vox), Roy Fishell (organ, piano), Chiquis Lozoya (guitar, vox), and Devin Morrison (guitar, vox) have been winning fans with their version of Golden Era reggae for more than 20 years.
