SellABand (unfortunate name, that) is a potentially interesting new music publishing model. If you’re a band, you publish your demo music on SellABand’s site. Listeners who like your music can plunk down $10 for a “part”. When 5,000 parts have been sold, SellABand spends the money to hire you a studio and a producer and publish your music in a special edition CD (for the listeners who bought parts) and on their site for free. SellABand’s advertising revenue is split, based on a band’s share of download activity on the site, between SellABand, the listeners who bought parts in your band, and you. You also sell CD’s through the site and split the proceeds with the listeners who sponsored you. Perhaps overly complex, but could do a good job of enabling fans and bands to make it happen.
