Bar none-—and I saw them all-—Hendrix & Vanilla Fudge. Jimi just past his prime of 1 year earlier, Fudge most amazing musicians I ever saw.
Then I moved to Austin in '83 for college and no real big rock acts come here often (I remember the Dead were here in the fall of '83 and Pink Floyd stopped for a show in '89). Most of the music here these days is coming from the over-commercialized festivals the city and the promoters makes millions from the hipster douchebags on(ACL, SXSW, etc...). Greed has absolutely ruined the live music scene here, IMO.
