The first concert I ever went to was 'Mountain' (Leslie West's band) at the Spectrum. Concerts at the Spectrum back then (c1970) were known as "dance concerts". No assigned seating, just $7.50 or whatever to get in the door. The opening acts were Black Sabbath and Humble Pie. I went mainly to see Black Sabbath - - it was their first US tour.
Anyway, between acts the announcer said that next Saturday the Allman Brothers Band was going to be at the Spectrum. I remember asking my buddy if they were any good. Boy, do I wish I had seen that concert. It was the same tour they were on when they did their Fillmore East live record. Great, great record.
Mountain, Sabbath and Humble Pie? Where’s my time machine?!?!
Not the best performance or video, but an interesting location
