Tom Morello has stirred up fears that Rage Against the Machine will not perform together again after saying their future is "unknown."
He added that the band have no plans to tour, but acknowledges that their music has some resonance with the receipt street protests in Brazil and Turkey.
"All I can say is that the music we created is so vital and contemporary to what is happening today in Sao Paolo and Istanbul," Morello told the NME. "Those songs are being played over PA systems and sung in the streets wherever people are standing up for their rights. In that regard, the band is alive and well. Whether or not we play any more shows is ... unknown."
Last year, he also said that the band had no plans to record new material. "When bands make albums it's because everybody wants to, and that's not the case with Rage Against The Machine at the moment. Everyone in the band gets along very well, we consider each other friends and comrades in arms, but people sometimes don't feel ready to do it ... If at some point Rage were to get it together to work more I would be open to that, but that's not on the table right now."
Rage Against the Machine most recently reunited in 2010 after an online campaign to get their song "Killing in the Name" to beat X Factor to the Christmas Number 1 slot.
