STS9 (Sound Tribe Sector 9), who will be on tour this summer is support of their soon-to-be released studio album "Peaceblaster," announces the last leg of their travels which includes stops in San Francisco and Berkeley. After playing their Bay Area shows, their summer will culminate with two huge headlining shows at Red Rocks Amphitheatre.

STS9 is known nationally as one of the premiere genre-blending, high-octane groups out there. Their live shows are always energetic, with songs lasting minutes upon minutes as the band members build upon riff after riff of music. They achieved their popularity by playing various San Francisco venues like the Fillmore and the Warfield.

These are shows that can't be missed. For ticketing information, check out the STS9 Store.
