Dylan, Dre on Grammys

THE PLOT THICKENS: The latest rollout of Grammy performers is particularly intriguing, with none other than Bob Dylan teaming with postmillennial folkies Mumford & Sons and the Avett Brothers in “a special salute to acoustic music.” Perhaps the Bard will actially ditch the electric piano he’s been attached to in recent iterations of his Endless Tour in favor of an acoustic guitar for the occasion—but never assume anything with Bob. In another coup, Dr. Dre will make his first live TV performance in more than a decade, joining his longtime collaborator Eminem and Maroon 5 frontman Adam Levine. And here’s the latest batch of presenters: Zac Brown, Eva Longoria, Jennifer Lopez, Ricky Martin, Packers linebacker Clay Matthews, Glee’s Matthew Morrison, Ryan Seacrest, Jason Segel, Keith Urban and will.i.am.
