Kiss - Live in '75
I've never been particularly impressed with Kiss, both as a studio band (I find a lot of their recordings pretty clunky) and as a live band (since it seemed that they relied heavily on the makeup, pyro and other tricks). But this clip from early 75 at the Winterland Ballroom is pretty badass.
It's clear that Paul Stanley is the key to their onstage energy, since Gene Simmons seems to have two moves and Ace comes from the "stroll around" school of rock guitar. Paul, meanwhile, jumps around, headbangs and windmills like crazy - good stuff!
I should say I like it in black and white too - gives it a little creepy mistique.
