Purling Hiss at Brooklyn Night Bazaar
Hurling P... I mean, Purling Hiss are one of those bands whose lead singer completely steals the show. This guy's aiming for Rock God status. Their sound is so lo-fi that it's a bit of a shock that end up being so impressive live. They have some songs over on BandCamp. If you listen to 'em, turn the volume up!
Diarrhea Planet at Brooklyn Night Bazaar
Ignore the name for a moment (if you can manage). These guys are totally nuts on stage. Four guitarists means that at least one person is always flailing about or messing with the audience or something fun like that. And dang, do these guys ever rock while they're at it.
You can hear them on BandCamp or their Blogspot site. As an extra added bonus you'll learn how to spell "diarrhea" properly after seeing it so much.
