Looking for the most extreme musical event of the summer? Then look no further and prepare yourself for The Power of the Riff Festival at the Echoplex on August 11’th! The Echo and Echoplex are well known for bringing underground tunes to happy hipsters in L.A and surrounding areas, but for an entire day the Echoplex is devoting itself to bringing out some of the most extreme local (and non-local) metal bands that Southern California has to offer. This is a crusty, metal purist’s dream. The big name at The Power of the Riff Festival is the enigmatic Sunn O))), which is really just icing on the crusty cake. Check out the line-up and read all about the wide array of extreme musical acts coming out for this awesome event. The Echo always seeks to fully represent whatever scene is getting featured, which is why this fest is going to be awesome. There will be a record swap meet, local record labels hanging out, gourmet food trucks, and just cool people enjoying some crazy music all day. Get your tickets here and save a few bucks on admission. It will be worth every penny. Oh, and as an added bonus, this event is all ages, which means that even the youngest of Discharge fans can come out and spend the day raging.
