Your First Concert was.....

The Grateful Dead at a Chinese New Years show in Oakland about 20+ years ago.
They sucked so bad as to be unbelievable!
(And, to top it off, the acoustics in the place sucked too.)

However, several years later, I went to another Dead show, where they were backing up Bob Dylan, and it was much, much better.)

11/17/73 - Focus, with the Spencer Davis Group (no Steve Winwood) opening, at the Felt Forum (now known as The Theatre at Madison Square Garden).

My friend and I bought tickets just a few days before the show and ended up in a row of folding chairs set up in front of the regular seats. Man, it was loud.

Next up would be Yes at MSG on the 'Tales From Topographic Oceans' tour.

I saw Focus as well. They played Hocus Pocus and variations of it the whole show. It was still fun. I saw the Allman Bros just when Duane died but Berry was still alive. They did not cancel the tour.

Joe Walsh and James Gang for openers, followed by REO Speedwagon.
