Saw them for the first time in the summer of '75 at "Tempe Stadium" as it was called then. It was hot as hell during the day - we're talking Arizona hot - but the night came down as Aerosmith took the stage, then came Johnny Winter, then the ZZs. I haven't been the same since. I spent months researching what in the hell a "Rio Grande" amp head was, before I figured out his backline was a pile of "re-branded" Marshalls. Dusty had them too, oh man they they were so "Texas" heavy and laid it down for over two hours. The Rev is my favorite American guitarist, next to some guy born in the Netherlands and transplanted to Kalifornia. Thank the Gods for that bit of circumstance. . .
