Mechanicsburg, Pennsylvania keyboardist and singer Robert Richardson has been through a lot in his life, not all of it positive. But he's taken a difficult past and turned it into a productive present with his band Cell15. Following on from the success of their 2014 debut Chapter One, they've just released their sophomore effort River Utopia, and you'll hear his interview with host Mark Ashby about the spread-out nature of the band, why sharing his story in recovery is so important, and whether or not he might have an epic-length track in him someday. The Prog Squad archives are mined for an episode from 3 July 2015 just after the passing of Yes' Chris Squire, but wherein the usual panelists and guest Geoffrey Langley of the Twenty Committee talk Primus, Rock and Roll Hall of Fame, and rare tracks they'd love to hear live. And appropriately enough, the Triple Track Special's theme this time is "utopia," with additional tracks in that vein from Factory of Dreams and Hawkwind. Find Cell15 online at www.cell15.com.
