So Amazing: An All-Star Tribute To Luther Vandross, due Sept. 20, the album celebrates the music of the late R&B icon through covers of his classic hits from such artists as Alicia Keys, Celine Dion, Fantasia and Usher.

"No one had ever heard of anyone that sounded like Luther," says Mary J. Blige, who puts her spin on the Vandross classic Never Too Much. No one heard anyone that brought that much soul," she tells Billboard.

In a posthumous duet, Elton John sings the Burt Bacharach/Hal David song Anyone Who Had a Heart alongside the original vocals Vandross recorded for his 1986 Epic Records album Give Me the Reason. In an intriguing choice, Wyclef Jean puts his stamp on Luther’s Always and Forever.

Keys and Jermaine Paul tackle If This World Was Mine, while Dion reworks Luther’s Dance With My Father, the title track of the album released in 2003, shortly after he suffered a debilitating stroke. Vandross died on July 1, 2005 of complications from the stroke. He was 54.

The tribute also features Aretha Franklin singing A House Is Not a Home, Patti LaBelle belting Here and Now and Beyoncé covering the title track.

Others featured on the tribute include Jamie Foxx (Creepin), Donna Summer (Power of Love/Love Power), Fantasia (Til' My Baby Comes Home), John Legend (Love Won’t Let Me Wait) Usher (Superstar) and Babyface (If Only For One Night).
