Well in a recent interview with TheVine, Black Keys drummer and producer Parick Carney revealed that the band are sitting on a second Blackroc album of nine songs that "were never released that are pretty much done," with no plans to ever be released. But more interestingly, that they recorded an entire album's worth of material solely with RZA, that has also been resigned to the archives.
"We have a lot of hip-hop stuff that we did with other people that is just never gonna come out," Carney told us. "Like, we did basically a full record with RZA in Los Angeles. Then we have these nine songs from this second Blackroc session. But yknow, a lot of its just experimenting. Some of its really good, I think, and some of it is not so good. But I think theres just too much of a novelty factor to keep doing it over and over again. Doing it once was enough. I think it might get old if we keep revisiting it. But maybe one day that stuff will see the light of day. I dont know.
