I was lucky to see the Experience in '69, in Indy. One long set that ended oddly.
I'd never heard of the opening band, Chicago Transit Authority, so that was a real treat.
While Mitch soloed, Noel and Jimi went behind their amp stacks and snorted a bit, not uncommon on stages then.
The crowd around the stage kept yelling for his hits, and Jimi said he just wanted to play blues. (one a-hole kept flashing a camera flash in his eyes)
at some point Jimi held his hand up in the 'Peace' sign, then changed it to the 'finger', dropped his Strat, screaming with feedback and walked off.
Jimi's music and Mitch's drumming lifted rock drumming a notch, Fire, Manic Depression and the like sent us cover band drummers to the woodshed.
