MJ's live performances are very hard to fetch. But when you find them, they're greatness. He gives it his all, whereas his full-set performances took a lot out of him, and it was less crisp from the technical wizard. There are a ton of full-set videos, but his live, single-set performances are like finding a gold nugget in a dry river bed. He didn't like doing them, they were daunting to him.
My three favorite live MJ performances:
(The obvious, pure art, all-time best act) Motown 1983
Grammy Awards 1988
Super Bowl 1993
This gem is so unworldly fantastic. There's a version that I can't damned find, that I've seen before, that has his shirt change colors, the way it was originally aired. I recently read the original LA Times review, and, even then, while he didn't win anything in 88 for Bad (he was ROBBED), they knew they just saw something extraordinary
