On the heels of a break-through album, Toys in the Attic, and three hit singles -- Walk This Way, Sweet Emotion, and the re-released Dream On -- Aerosmith sought to record an album that would capture the electrifying power of their live shows. So they brought a mobile recording studio to their rehearsal space outside Boston, and laid down the tracks for one of rock's greatest-ever albums, Rocks. Released on May 3, 1976, it proved to be a huge success, reaching number 3 on the Billboard charts and being named by James Hetfield, Slash, and Kurt Cobain as one of their all-time favouroite records. Randy Renaud marks its 50th anniversary on the Chronicles of Rock.
