Beck can be out there a bit, but so were most greats. Srv getting booed harder and harder at each song during the monterrey jazz festival is likely the coolest show ever captured on film. He has just broken out, and they all thought he was fake, so they booed him. He obviously didn't understand it, so he just kept playing harder and harder through the set until its over and he walks off completely confused. If you can hunt down the dvd it's absolutely incredible. He plays the next year or so and is rightfully adored, but that first one is so brutal and raw. Here's some from it.
