Don't forget Metallica at Stubb's tomorrow night - though I'm sure that one's not free LOL.
Maybe you'll run into BFrank somewhere too.
It was "free" if you had a badge or wristband and got there early (both of which I did). In line about 6:45 and they hit the stage at about 9:45 - played for about 90 minutes. Pretty insane, for sure and great to see them in a small, 2,000 "seat" venue (no seats) and up close.
Also saw Earthless (w/J Mascis) at Habana on Friday afternoon. Pretty intense stuff. One long jam for about 45 minutes.
Other highlights: Dan Auerbach, Peter Murphy, Jon Dee Graham, the Silos, Maserati, Hold Steady, Choo Choo, Iguanas (w/appearance by Flaco Jimenez), Dave Alvin, Roy Head & the Bo-Keys, Silversun Pickups, Waco Bros.
