System of a Down and The Deftones join forces - Play to 50,000 people

The concert was the first of a series of shows that Golden Gate Park plans to host in the future. The venue is the home of the annual Outside Lands festival, which took place just a week prior to the System of a Down and Deftones show. The Mars Volta, Viagra Boys and VOWWS performed as well.

Several news outlets reported that 50,000 fans attended the concert Saturday night, and 90 percent of the attendees were from outside of the San Francisco area

Luckily for us, a couple of good bastards in that crowd filmed the performances, check them out below!
