JamBase will curate a music festival at George, WA’s The Gorge Amphitheater on July 5 and 6. The two-day JamBase Live event will feature approximately a dozen acts on the festival’s main stage, half of which have never performed at The Gorge. A mailer from the website also hints that several of the repeat performers will return to play The Gorge after as long as a decade. The festival’s full lineup will be confirmed in the coming weeks.
