Following the current success of El-P's Cancer 4 Cure, it seems the last thing the rapper wants to do is sit back while he enjoys this rich vein of form. The Brooklyn MC took to twitter this week to announce that Killer Mike and himself are going to be working together on a new side project, "where we both rap. why? because we are bastards, that's why."

This follows on from the pair teaming up earlier this year to work on the Killer Mike album, R.A.P. Music where El-P had complete reign over the production. We're not sure exactly what the project will be but going from the teasing tweet, we can expect both MC's to drop verses in what could be one of the biggest collaborations since, dare we say it, Watch The Throne.

More news as soon as we have it but in the mean time why not get a taste of things to come by checking out a track they both rhymed on taken from R.A.P. Music, 'Butane (Champions Anthem)'.
