TWELVE DREAM OF DR SARDONICUSSpirit: Randy California (guitar); John Locke (keyboards); Mark Andes (bass); Ed Cassidy (drums). Includes liner notes by Marty Pekar. After three albums with producer Lou Adler (who had also signed them on his label, Ode), the band brought in David Briggs, who'd previously worked with Neil Young. A real sense of camaraderie and experimentation runs through this entire work, which took longer to record than any previous Spirit effort. "Nature's Way"
