While San Francisco may, these days, be better known for more jangly and psych-inspired taste, Happy Fangs is a SF-based band making uncharacteristically badass rock 'n roll. And it's refreshing to get a kick in the ass from something with a little more rock power. Originally a duo -- with such a cute, "met sharing a practice space," story -- it quickly became clear that Rebecca Gone Bad and Mr. Cobra needed a live drummer who could match their fierceness to take the band where it needed to go. Appropriately, their search for "a woman who plays drums as hard as Dave Grohl" led them to Jess G., and she's more than capable of living up to the expectation. Musically, there's a lot of pop in their hard rock (or perhaps it's the other way around) and their theatrical-tinged performance has more than a little bite.
