The Harmony Festival has been announced for June 12-14 at the Sonoma County Fairgrounds, Santa Rosa, CA.

The event will feature a professional skate expo and competition dubbed the Eco-Cup, featuring many of the biggest names in professional skating competing on a 175-foot long mini Mega Ramp with a mind-blowing 30-foot drop from an 18-foot vertical ramp (the equivalent of a three-story building). The event will also include the first-ever "best trick" rail contest over a 20-foot gap with $40,000 in prize winnings.

Music for the show will be provided by the Dead Kennedys, Bad Brains, Pepper, Rebulution, Hightower, Tall Black Girls, Zepparella, Egypt Central, local bands The Whiskey Thieves and American Drag, and MC Radioactive.
