Switch on any classic rock radio station and it's likely that within minutes you'll hear the handiwork of producer and engineer Glyn Johns; over the course of a career that had its beginnings during the British Invasion, he assembled an extraordinarily impressive body of work including landmark recordings by such perennials as the Rolling Stones, the Who, the Eagles, Eric Clapton, and the Steve Miller Band. Born in Epsom, England, on February 15, 1942, Johns originally began his career as a performer, issuing a handful of singles on the Pye and Immediate labels during the early '60s. The singles went nowhere, however, and soon he began pursuing a career as an apprentice recording engineer under legendary producer Shel Talmy. By 1965, Johns was engineering sessions by the Rolling Stones, with his credit later appearing on classic LPs including 1967's Their Satanic Majesties Request and the following year's Beggars Banquet. He also engineered material for Led Zeppelin and Spooky Tooth.
