In the fall of 1955, poet Allen Ginsberg unveiled his epic masterwork "Howl." That poem, and the man behind it, were the focus of last night's star-studded 60th anniversary celebration in downtown Los Angeles at the Theatre at Ace Hotel. (Yup, the same place as last week's "The Music of David Lynch" show.) For Rolling Stone, I reviewed "A Celebration," which featured everyone from Courtney Love to Tim Robbins to Will Forte to Nick Cave. Hope you enjoy.
