U.F.O.

One of the heavyweights riding the British Heavy Metal wave in the late 1960s, UFO stands tall in the canon of rock ‘n’ roll. We’re partial to Phenomenon, an early album that opened the floodgates for UFO’s heavier sound — their identity. Chord-chugging classics like “Doctor Doctor” and “Rock Bottom” tap into an important part of early metal history. Even now, decades removed from their heyday, the band still throws down a head-banging set. (Eric Sandy)
