The collection of unreleased material, titled Deliverance, comprises newly-discovered studio recordings from 2006 to 2008 and was due to be available on Friday (21Apr17).

The Sign o’ the Times hitmaker co-wrote and co-produced the songs with George Ian Boxill, who was his mixing and recording engineer for five years from 2004. In the year since Prince’s death, Boxill has completed the arrangements on the tracks, finishing the production and mixing the songs.

However, the planned release of the EP has been hit with a lawsuit as Prince’s estate and Paisley Park have filed a federal lawsuit against the sound engineer for control of the Deliverance tracks, according to

The lawsuit estimates the value of the new songs at more than $75,000 (£58,400).

Boxill is accused of refusing to return the tracks in violation of a contract he made with the Purple Rain icon. The lawsuit was initially filed in Carver County district court on 14 April (17), but was re-filed in federal court on Tuesday (18Apr17) because Boxill works in California.
