Apart from the emotional reward of making a plan possible, this is decided by the artist. At the very minimum, Fans get a download of an album. The artist can decide whether or not revenue is shared, (limited edition) CDs are awarded and if there are any extra incentives. With these extra incentives, Artists can showcase their creativity. Autographed T-shirts, lifetime backstage passes, autographed instruments? Remember that it is the Artist's responsibility to live up to any promises made.
