Silver (or maybe Sliver, as we've read contrasting reports) is expected to include three previously unheard songs alongside its collection of 19 other odds and sods. Kurt Cobain's daughter, Frances Bean, is said to have been involved in the record, picking the title and artwork.
The manager of the Cobain estate, Peter Asher, has said that it is the intention of Courtney Love and himself to involve Frances Bean in as many Nirvana-related business decisions as possible. She has cool ideas, apparently.
DiS has no release date for the new compilation as yet. Sorry.
