When Adrian Belew was brought in to record his mind-bending guitar solos on what became Taking Heads’ landmark 1980 album Remain in Light, he felt an unprecedented amount of freedom. He was presented not with almost-finished songs but unstructured grooves that felt like vast open spaces for him to color in. That he did, brilliantly, and Belew and Jerry Harrison of Talking Heads are now revisiting this album with a live tour. Of course, Belew’s resume covers a lot more ground, including guitar wizardry with Frank Zappa, David Bowie, Paul Simon and Nine Inch Nails, his stint as lead singer/songwriter of King Crimson and his own solo career. How did each of these collaborations stretch him? And was he really asked to replace David Byrne in Talking Heads?
