A never-before-released Bob Marley song believed to have been recorded in a Miami bedroom in 1979 will be found on the upcoming compilation "Africa Unite: The Singles Collection." Due Nov. 8 via Island/Tuff Gong/UME, the set features "Slogans," the master tape of which was revisited in 2003 by Marley's sons Ziggy and Stephen.

In addition to adding their own parts and producing, the Marleys drafted Eric Clapton to record a guitar part for the finished version. Ziggy first revealed the existence of unheard Marley material to Billboard.com in 2003.

"I didn't know any of these songs," he said at the time. "The way he was playing the guitar on one song that I heard, it was like jazz. It wasn't what you would expect from him at all."

"Africa Unite," which collects early recordings as well as Marley's biggest hits, is rounded out by a new remix of the title track from the Black Eyed Peas' will.i.am plus Ashley Beedle's mash-up of "Get Up, Stand Up" and youngest Marley son Damian's "Welcome to Jamrock."

As previously reported, Nov. 8 will also see the release of the DVD "Live! At the Rainbow," a 1977 London concert originally released in 1991 on VHS. A sample of Marley's "Johnny Was" can be heard on a newly released Notorious B.I.G. single, "Hold Ya Hand."
