What: 2013 Scion Rock Fest

When: June 1

Why: Scion have been supporting underground metal for years, and they've put this festival together completely free of charge, although an RSVP is required. The lineup is incredibly solid and ranges from underground metal legends to up-and-coming acts. If you're in the Memphis, Tenn. area, start training your neck for some vigorous headbanging.
