Alice Cooper (That Tent: Saturday, midnight)
Perhaps the biggest wild-card at Bonnaroo this year is Alice Cooper's Saturday late-night slot, where the O.G. shock-rocker plans to teach a a hard-rock history lesson to festivalgoers. The 64-year-old Cooper recently told Rolling Stone that he plans to bring his guillotine and enough fake blood to soak the first 20 rows. "It'll be the full-out Alice Cooper show," said Cooper. "My band has the instruction: kill the audience."
