A few weeks back, we compiled a list of the 2011 Decibel Festival headliners that had been announced to date. Earlier this morning, the Seattle-based event, which has become one of the premiere electronic music events in the US each year, unveiled a more complete program. Along with big-name headliners such as Moby, Amon Tobin, Zomby, Motor City Drum Ensemble, Bok Bok, Martyn, Girl Unit, DJ Krush, Green Velvet, dOP, and others, the festival has announced an impressive list of showcases throughout the five-day affair, including a number of musically themed themed parties and some bills sponsored by the likes of Red Bull Music Academy, Night Slugs, Dropping Gems, and others. Decibel 2011 runs from Wednesday, September 28 through Sunday, October 2. The complete showcase list is here, presale tickets are available through Bookr, and the latest Decibel flyer has been posted below. Give it a look and start drooling over the list of artists involved.
