This is beautifully loud news.
Alternative Nation is reporting that, according to Rage Against The Machine / Prophets of Rage / Audioslave drummer Brad Wilk, Zack de la Rocha is making music! Brad was on Let There Be Talk and said that Zack has never stopped working, plus that all of the RATM guys are on good terms.
Maybe one day that can happen again, and in the meantime it seems like Zack has some project that we'll be learning more about soon.
