The ones listed below are the ones I can remember seeing. Probably at least a few left off of the list that accompanied the Grateful Dead (went to several of their shows) Grand Funk Railroad (may have been accompanied Humble Pie but that was long ago in 1970) or that accompanied some other bands.
Alice Cooper
Alison Krauss & Union Station
Black Sabbath
Blondie

Charlie Daniels
Frank Zappa
Genesis
Grand Funk Railroad
Grateful Dead
Hot Tuna

Led Zeppelin (Well almost; waited on lines for two shows for a total of about 2 or three days in the wintertime and got around 10 tickets for each show for myself & friends. Came down with appendicitis and had surgery when they played at Nassau Coliseum and at Madison Square Garden. When at the Garden they allowed a NYC FM radio station to broadcast it live so at least I heard them while I was laid up in my hospital bed.
