Blue Oyster Cult's first album was a masterpiece; Tyranny and Mutation and Secret Treaties had great material but sounded like they were being played on the dead run (which they were, in a sense, the band was touring so much at the time); On Your Feet or On Your Knees was the best hard rock/heavy metal live album of the mid-1970s. They began losing me after Spectres, the material wasn't up to the par of the first six albums, but if they had to leave Columbia in due course they sure did go out with a bang with Imaginos . . .
Actually plenty to speak about. Lead guitarist - Buck Dharma - supposedly started playing when he was 17. Pretty late in the game. Heard another 70's great - Ronnie Montrose - started about the same age. Anybody else heard those stories.
Next, BOC had a pretty large laser show for their time. They did some big shows for a while - had Rush as a backup band on one tour I saw.
They are not for everybody, but they had some cool songs.
I do believe it was someone in the road crew. It was pretty intense having seen then a few times. Like many bands of the 70's, it's too bad High Def digital filming was not around for their concerts. Would have loved going back and seeing 70's bands like Golden Earring, Wishbone Ash, Foghat, name your next 100 bands, etc. in the their 70's peak.
