I thought I'd put my two cents worth in on performers I'd like to here in the concert vault (in no particular order:
Buffalo Springfield
Julie Driscoll
Ten Wheel Drive
Circus Maximus
The Nice
Mose Allison
Savoy Brown
(By the way, does Wolfgang's Vault have recordings of all the performers listed in the "All Performers" list one can get to from the WV home page?)
Random comments (you can skip this part)
Julie Driscoll recorded an incredible version of Season of the Witch (in the mid to late 60's I'm guessing.
Living in the midwest my whole life I never went to either of the Filmores but I did get to hear Ten Wheel Drive at the old Olympia, former home of the Red Wings, in Detroit. Great seats about 10 rows from the stage, but it did get a bit cold after a while with chairs on whatever they had covering the ice.
There used to be some good tunes by the Nice on Vault Radio when it was in it's original incarnation. I hope they'll show up in the Concert Vault some day.
