I said this last week, and I’m going to say it again this week. Austin City Limits needs to figure out a way to air full performances instead of just showing thirty minutes of each set per episode. Sonic Youth and the Black Keys did their best to share sixty minutes of PBS airtime. Check out their performances below.
