Soul legend Al Green says it’s been all love and happiness working on his next album — a duets project produced by Roots drummer Ahmir “Guestlove” Thompson that will feature collaborations with Anthony Hamilton, D’Angelo and possibly Alicia Keys and Joss Stone.

Green told Billboard.com that he and the Roots already have laid down 15 songs at Electric Lady Studios in New York for the tentatively titled “The Duet Album.” Blue Note sources told Billboard.com that they’re trying to arrange studio time for Green in August, September and October. They hope the album will be finished by November, with an early 2008 release expected.
