Filter Magazine's cosmopolitan music festival brings together big names and buzzworthy bands from around the world. Discover your next favorite artist while venue-hopping around Echo Park for three days with performances from Ladyhawke (New Zealand), Ash (UK), the Juan Maclean (US), the Album Leaf (US) and more. Past years' creative performance spaces have included the local Whole Foods and inside flying airplanes. But take note: The down-to-earth fest has a strict "no fashion headdress" policy.
