It was recently reported that 3/4 of Rage Against the Machine (everyone except Zack de la Rocha), Chuck D of Public Enemy and B-Real of Cypress Hill formed a supergroup called Prophets of Rage. The members have now confirmed the existence of the group, and announced that their first show will be at LA's Whisky A Go-Go tonight (5/31). Proceeds will benefit PATH, "a family of agencies working together to end homelessness for individuals, families, and communities."

The group will be performing material from Rage, Public Enemy, and Cypress Hill, as well as new songs. According to an interview with Rolling Stone, Tom Morello says they already have one new song completed, "The Party Is Over" (which was written on the band's initial teaser poster). In the same interview, bassist Tim Commerford confirms that he "spoke to Zack [de la Rocha] and got his blessing" for Prophets of Rage to play RATM songs. He continues:

You're never going to replace Zack, and we aren't trying to do that. He's a unique artist and showman. It's going to take people that I know he looks up to and that he idolizes and that he's inspired by. We're going to plug them in and see what they can do with these songs, because at the end of the day it's all about the songs. The songs are needed right now, they really are. This is gonna be some cool shit.
