Commemorating what would've been Prince's 60th birthday on Thursday, his Estate announced that it will release the first full album titled "Piano & a Microphone 1983" since the deluxe edition of "Purple Rain" last year.

It is a collection of solo songs recorded at home by the singer. 

The 'Purple Rain' hitmaker tragically passed away in 2016 from an accidental fentanyl overdose at the age of 57, leaving behind a vast collection of unreleased music which was known only as "the vault".

The estate released the first song from the album, a cover of the spiritual song "Mary Don't You Weep", which will be featured during the end credits of Spike Lee's "BlacKkKlansman" film, which will be released in August, reports variety.com.

The album features versions of "Purple rain" and "17 days".

While the album shares a title with Prince's final concert tour, the album pre-dates it by some 33 years.
