Rockin , originally released in 1972, represented a back-to-basics album for The Guess Who. The twin-guitars of Kurt Winter and Greg Leskiw power one of the band s hardest rocking releases. Yet in true early 70s Guess Who fashion, Rockin features an all-inclusive definition of rock, from the heavy riffs of opening track and single Heartbroken Bopper, the 50s-styled boogies Get Your Ribbons On and Running Bear, the harmony-driven Smoke Big Factory, the socially conscious Guns, Guns, Guns, and the psychedelic multipart suite that closed the original album. A longtime cult-favorite among their fans, The Guess Who s Rockin has been augmented with two previously unreleased bonus tracks including Lost Sheep, a dry run for the Hi Rockers! medley that arguably betters its originally released counterpart.
