When Billy Bragg, Tom Morello and other rockers visited the Travis County Correctional Facility near Austin, Texas in 2010, it obviously wasn't the first time somebody had rocked a jail. Country legend Johnny Cash, of course, did it twice -- once at Folsom Prison, once at San Quentin -- but there's something about this recent gig that's just a bit more ominous. We got it! It's because it was part of the annual SXSW festival. How very bizarre.
