There’s no use speculating whether Kurt Cobain would have wanted his sketches, throwaways, pranks and duds entered into the public record; the dead don’t get to speak for themselves, and suicides in particular renounce their right to self-representation. So this just-in-time-for-Christmas collection unashamedly summarizes last year’s just-in-time-for-Christmas With the Lights Out, adding three demos withheld from the box. Unless you’re thrilled by the moment when Cobain coughs in the 1985 gag “Spank Thru,” these crusty discards add little to understanding his life or music. He was a genius, but he needed focus and motivation to balance his urge to be sloppy and offhand. And he needed Dave Grohl on drums. Here, he rarely has any of those. Judging from the cover art—a mess of cassettes with demos, riffs and “funny noises”—this could go on for years. DOWNLOAD: “Oh the Guilt,” “Blandest”
