You like Noise Rock? Yeah well anyone who doesn't doesn't deserve testicles (or a fanny) so get ready for BILLY BAO!
The closest band that in my eyes comes close to Billy Bao would be the legendary Brainbombs. Maybe some Hospitals in the mix as well as some Flipper cause all the best rock bands sound a bit like Flipper.
You can download their stuff from this rather spartan site which kinda functions as his bandsite:
Also notice how they have a much more interesting history then your standard white boy, middle class indie bunch.
Oh and they don't mind you downloading their stuff as they state themselves "BILLY BAO DOES NOT GIVE A FUCK ABOUT COPYRIGHT SO YOU CAN DO WHATEVER THE FUCK YOU WANT WITH HIS STUFF
THANKS TO THE BLOGGERS THAT SHARE BILLY BAO STUFF"
