At one point in Kurt Cobain: Montage of Heck, a new documentary about Nirvana singer Kurt Cobain, his widow Courtney Love says she told him, "You better buckle up because you ware not ready for this." The film, which includes interviews with Cobain and home videos, provides an up-close-and-personal look at the troubled rock star. It makes its theatrical debut tonight at 8:35 at the Cleveland Institute of Art Cinematheque. Tickets are $9. (Niesel)
