This week a gigantic Pink Floyd box set is released. What's remarkable about Pink Floyd Early Years 1965-1972 is that its 27 discs cover only the band's first seven years! All this week we'll think pink with some of the people who were there. On Friday — the day this collection is released — we'll talk with drummer Nick Mason about those early years. On Tuesday we talk to Roger Waters about his upcoming projects and politics. But we thought we should start with a man who, 50 years ago, witnessed and participated in those very early days. Joe Boyd was an American working for Elektra Records in London in 1966, and the group played early shows, before it had released any recordings, at the UFO Club, where Boyd was an owner. He'd go on to produce Pink Floyd's first single, "Arnold Layne." Joe Boyd is a critical figure in the British folk music scene and global music scene. If you love Nick Drake then you can thank Joe Boyd. His book White Bicycles paints some great images of making music in the '60s, including stories of Pink Floyd. He also has a podcast that's quite brilliant called Joe Boyd's A-Z where he goes through his remarkable record collection in alphabetical order, making insightful musical connections and telling personal stories. We suggest Pink Floyd fans listen to the episode on the letter I, for "Interstellar Overdrive."
