Madlib and MF Doom haven't worked together since recording their whacked-out, disjointed masterpiece, Madvillainy, in 2004. After a number of false starts, a remix album and various tracks on Stones Throw Records compilations, the duo has finally reunited -- the two are in California working on new material. Eastvillageradio.com DJ J.Rocc recently premiered a slew of snippets on his weekly Fat Beats Live show. Stones Throw confirmed the existence of a new Madvillain project, adding that TV on the Radio's David Andrew Sitek and rapper Mos Def are set to be featured on the album. The possiblities are mindblowing. Stones Throw has the radio rip of J.Rocc's show. [Pitchfork]
