The Decibel Festival, probably the wildest time you can have in Seattle, has been slowly unveiling the line-up for 2011, and has just released a slew of its main headliners. The city-spanning event boasts a growing roster that now includes the likes of Julio Bashmore, Moby, Martyn, Zomby, Motor City Drum Ensemble, Egyptrixx, Kyle Hall, Bok Bok, Girl Unit, Mike Huckaby, Mountains, oOoOO, Deniz Kurtel, and Kate Simko. As if that wasn’t enough, the festival will also mark the US debut of Amon Tobin’s (pictured above) ISAM live show—which received a nice blurb from us in our Mutek Wrap-Up. Decibel runs from September 28 to October 2, and advance tickets can be purchased via Bookr.
