Cool video alert. Some upstanding Internet citizen uploaded a full set from the Jesse Lacey (Brand New) / Kevin Devine acoustic tour that happened way back in the dark ages of 2007. The acoustic angst is in the replies.
In the replies you can see a video Jesse Lacey (Brand New) tossing his guitar (and nearly hitting drummer Brian Lane) at Lollapalooza. Since this is a heated controversy, you can also expect to see 100+ replies over whether or not Jesse was happy.
