Adrian Belew joins Eric in conversation. We talk about his early days discovering guitar as a kid in Kentucky, auditioning, working with and learning from Frank Zappa, memories of recording and touring with David Bowie, his long tenure in King Crimson, his varied solo and side projects (including working with The Bears, Trent Reznor and Steven Wilson) and  pursuits and we get into his new unique, interactive and constantly evolving music app, Flux.
