I mostly find that there's plenty of old and new 'real' dance music that's better and more extreme/noisy/'experimental' than some noise dood who just started listening techno last year and decided to have a go, or some dance guy who found out about black metal from some tumblr fashion blog and started making 'dark' music. :)
In terms of noise with dance/beat/rave element Ryan Jordan is doing some pretty great stuff, intense strobes triggering sound via crude handmade electronics. No recordings yet but there's plenty of video (not that video can adaquately capture the visual or sonic effect.) Someone's alreadu put footage up of his set on saturday night, it was INTENSE thru a proper club soundsystem:
