Contributors can choose a level of pledges ranging from the $10 “unpolished rock,” which earns them a free digital download of her disc when it’s made, to the $10,000 “weapons-grade plutonium level,” where she promises “you get to come and sing on my CD. Don’t worry if you can’t sing – we can fix that on our end.” For a $5,000 contribution, Sobule said she’ll perform a concert in the donor’s house. The lower levels are more popular, where donors can earn things like an advanced copy of the CD, a mention in the liner notes and a T-shirt identifying them as a “junior executive producer” of the CD.
