One of the most massively underrated bands in music. In part I think its because they suffered from something that happened to a lot of hard rock bands in the 70s-they had a hit single that wasn't really representative of their overall sound and it wound up being the thing most people remembered them by even BEFORE the SNL sketch-but Blue Oyster Cult created a ton of innovative, interesting music and managed to remain, at their best, still a hard rocking guitar band. They had more in common at times with bands like the Doors and Steppenwolf than they did with the metal bands they were marketed as being an American answer to, had some really magnificently surreal lyrics, and in Buck Dharma had perhaps the most overlooked guitarist in rock music. One of my favorite guitar solos period is the one he plays on the extended live version of Veteran of the Psychic Wars from Extraterrestial Live, that's just freaking amazing.
BOC's easily in my all time top ten of bands. Amazing, amazing band.
