Al Green's long-in-the-works album co-produced by the Roots' Ahmir "?uestlove" Thompson and keyboardist James Poyser finally has a release date.

"Lay It Down" is due May 27 via Blue Note and features guest vocals from John Legend, Corinne Bailey Rae and Anthony Hamilton, plus contributions from the Dap-King Horns, guitarist Chalmers "Spanky" Alford and bassist Adam Blackstone.

"I've never heard anything quite like it, 'cause I've never had anybody produce me other than Willie Mitchell," Green told Billboard.com last summer. "And when you give these young kids a shot at it, it's interesting to see the art they make. It's beautiful."

Green enjoyed his highest-charting album on The Billboard 200 since 1975 when "The Definitive Greatest Hits" debuted at No. 46 in early 2007. His last studio album was 2005 album "Everything's O.K."

The Roots' new album, "Rising Down," will arrive just before Green's project on April 29 via Def Jam.
