Rocks isn't the most famous Aerosmith album. With the possible exception of "Back in the Saddle," there's no song nearly as iconic as "Walk This Way," "Dream On" or "Sweet Emotion." But the album captures the band at their absolute peak. Hard drugs had yet to corrode the group's camaraderie, and they were churning out brilliant work like "Last Child" and "Rats in the Cellar." Even minor tracks on the 1976 LP, like "Lick and a Promise" and "Sick as a Dog," are fantastic. It's a raw, loose and bluesy sound they've never quite managed to top, and 37 years later the album sounds incredibly fresh.
