The Prince Estate just announced the release of new music. On Thursday they released the acoustic demo of Prince's "I Feel For You," originally made in 1978/79. It was released as "a limited 7-inch vinyl with the acoustic version on the A-side, and the original studio recording on the B-side." Prince's estate says that the recording "captures a 20-year-old Prince in a raw, intimate moment, and begins with the sound of the artist pressing the record button on a cassette tape recorder and picking up the acoustic guitar. Chaka Khan's version won two Grammys, including an award that honored Prince as a songwriter.
