Produced by Martin Birch (who produced Heaven and Hell for Black Sabbath), Cultosaurus Erectus was a return to both form and critical acclaim for Blue Oyster Cult. Kicked off by "Black Blade," simply one of the group's very best songs, the record boasted a muscular sound, re-invigorated songwriting and probably the finest heavy metal album cover of all time. "Monsters" (totally weird) and "The Marshall Plan" (totally, um, rock!) are highlights. Buck Dharma goes to town in "Lips in the Hills."
