Last april, the NME revealed that Matthew Bellamy was planning to do a sort of english answer to Rage Against the Machine with The Streets' frontman, Mike Skinner. The collaboration is now complete with the track "Who knows who" that leaked on the internet a few days ago. Muse's answer has been fast, they say they "are happy for it to be leaked unofficially". Indeed, according to Matt Bellamy: "The MP3 floating around ... was the result of a late-night jam session and something we did for a bit of a laugh featuring a blues riff (nb: inspired by Led Zeppelin's Heartbreaker) we have been playing live recently upon which Skinner recorded some vocals. It is not intended to be a serious release [...]."
The rumour had it that Muse would be performing a few songs with another band at the V festival in 2 weeks, The Streets seem to be the most likely to perform with them if the project is still running.
