We actually have quite a bit going on here in LA, more than the rest of the US. It seems like most people here are from the UK though.
Noisia, Netsky, and some others are at the Beyond Wonderland festival in March.
High contrast, Andy C, Marky, Hype, and Zinc are all at the Coachella festival in April.
We also have some weekly shows that go on in the city.
