PENTAGRAM, WINTER, PELICAN, TRAP THEM, MASAKARI, ALPINIST, ACEPHALIX, and ALL PIGS MUST DIE are the first confirmed bands for this year’s Power of the Riff fest in Los Angeles. The fest goes down Saturday, August 13, 2011 at both Echoplex and The Echo in Echo Park, with more bands to be announced.

Last year’s successful event featured the same two venues featured the participation of some killer bands like CORROSION OF CONFORMITY III, GOATSNAKE, REPULSION, BLACK BREATH, NIGHT HORSE, EAGLE TWIN, and many more. We can only expect the same fine selection of bands this year, and we’re already off to an excellent start!

Unlike last year however, this year’s edition of the all ages fest will not be a free, sponsored event. Tickets will cost $30 and can be purchased here.
