Stevie Wonder will feature on Mark Ronson's new album.
The 'Uptown Funk' hitmaker has teamed up with a string of guests for 'Uptown Special', including the soul legend - who appears on the first and last tracks on the record - Tame Impala's Kevin Parker, Simian Mobile Disco's James Ford, and Bruno Mars.
Mark teamed up with award-winning author Michael Chabon for many of the lyrics on the album, which is his fourth studio release.
He said: "I wanted lyrics to push farther than most of what's going on in R&B and pop today.
"I wrote Michael to ask if he'd be interested in writing lyrics for the album."
Other acts on the album include Keyone Star, the winner of an audition Mark held at the Jackson State University in Mississippi, and Andrew Wyatt of Miike Snow.
Meanwhile, Stevie has been praised by Elton John as one of the greatest singers and musicians of all time.
The 'Rocket Man' hitmaker told GQ magazine: "He's so multitalented that it's hard to pinpoint exactly what it is that makes him one of the greatest ever. Along with Ray Charles, he's the greatest R&B singer who ever lived. Nobody can sing like he does. As a keyboard player he never ceases to amaze me. I like to think I'm a pretty good musician, but he's in a whole other league.
"When people discuss the history of music, they will talk about Louis Armstrong, Duke Ellington, Ray Charles and Stevie Wonder - and they will still be the greatest."
