More material unearthed by RZA.

Wu-Tang Clan’s forthcoming 20th anniversary album, A Better Tomorrow, looks set to feature vocals by deceased member Ol’ Dirty Bastard.

The group’s de facto leader and production maestro RZA has dug up a selection of tracks and verses recorded by the wayward rapper, who died in 2004.

“RZA has a bunch of Ol’ Dirty tracks and verses that for years nobody’s heard and, from my last conversation [with RZA], we’re supposed to have an Ol’ Dirty track on there,” Wu-Tang’s Inspectah Deck told The Line of Best Fit.

“It may be by itself or we might join it on to another song. But Ol’ Dirty is going to be part of this album, that’s a fact.”

A Better Tomorrow was initially expected to appear in July but is now set for release in November – hear the jubilant lead single from the album, ‘Family Reunion’, below.

Like many deceased rappers, ODB has enjoyed substantial posthumous success. A hologram of the rapper – as well as one of also-departed NWA member Eazy-E – is set to appear on the Rock The Bells tour this year, following the bizarre spectacle of Tupac’s hologram at last year’s Coachella.

The reunited Wu-Tang Clan play London’s Brixton Academy tomorrow, 26 July.
