August 13 [7:55 EDT] -- Not only will this summer's Rage Against The Machine/Wu-Tang Clan/Atari Teenage Riot tour offer the expected overdose of intensity, but it will also serve up some musical surprises as well.

On the second date of the tour, in Atlanta on Sunday night, Wu-Tang's Rza joined Rage for some freestyling on "My Country 'Tis Of Thee" [800k Live QuickTime] of all songs.

"We've got more songs from the record," Rage guitarist Tom Morello told MTV News of the impromptu jam after Sunday night's show. "There was a brand new song tonight, you know, and there may be a brand new one tomorrow. You never know, that was a one-and-only so far of that version, that thing we did with Rza tonight."

"We just made it up," Rza explained.

According to Morello, fans could be seeing more of these spontaneous collaborations throughout the tour.

"We do that a lot. It's always great to bring on artists we admire," Morello said.

The Rage Against The Machine tour, with the Wu-Tang Clan and Atari Teenage Riot opening up, will play Charlotte, North Carolina on Wednesday.
