On the Monday after Bonnaroo last year, I left the farm completely drained. While our shuttle winded its way off the grounds, past crews breaking down the stages, I spotted the giant Mr. T float. As it disappeared from sight behind a row of trees, I considered his waving, ever-smiling visage a final farewell. After all, what could top that Radiohead set? Well, needless to say, I'm headed back. And whether you are or are not attending this year, press play on this festival preview to hear from some of the best acts performing this year.
