Fela Kuti, by far. That show, absolutely nothing else existed, probably best performance in the world.

Second place Henry Rollins, I almost sat out his set because he was so snooty to everyone in the club but holy crap.

And Marcus King has such charisma - he is a pudgy not particularly handsome dude and was wearing an unflattering outfit but I swear he transformed, not physically exactly but is so compelling on stage - he picks up the guitar you forget about his looks. I find that almost the definition of cool, in a way. Transcendent.
