This week on Transmissions, we’re sitting down with a genuine legend: Joe Boyd, author of And The Roots of Rhythm Remain: A Journey Through Global Music, out September 24 from ZE Books. On the front cover of the book Brian Eno—a venerated saint in the Aquarium Drunkard canon—declares, “I doubt I’ll ever read a better account of the history and sociology of popular music than this one.” Boyd joins us to discuss the book and his work with Nick Drake, Fairport Convention, Sandy Denny, and much more.
