Elvis Costello is conducting a little experiment with his new album: It won't come out on CD. Titled Momofuku and due April 22 from Lost Highway, the album will be available–at least in physical form–on vinyl only, with a download code included in the LP. (Of course, many indie labels like Sub Pop and Matador have instituted this vinyl-plus-download model, although they haven't precluded CD versions of the same releases.) Momofuku will presumably be sold as a download, as well, and it's entirely possible that a CD version will be released at a later date.
