England's big beat provocateurs the Chemical Brothers have been criss-crossing America of late, and the duo joined hit-making DJ Fatboy Slim last Saturday at the Red Rocks Amphitheatre in Colorado.

Red Rocks has gained prominence as the locale of choice for live albums from acts such as U2 and the Dave Matthews Band... a pretty far cry from the DJ-ing duo, whose roots are firmly planted in the U.K. rave scene.

The Brothers, a.k.a. Tom Rowlands and Ed Simons, can adapt easily to either studio work or live shows, but as Rowlands imparted to MTV Online, there's a definite difference between the two.

"We've got no desire to sort-of replicate the recorded version [of our music]," Rowlands told MTV Online. "For us, the definitive version lives on the record, and when we play live, it's a chance for us to really play around with it and often create new things."

"A lot of jamming goes on," Rowlands continued. "We find that machines you work with, because we work with them such a long time, it's like, very intuitive, and we can make new songs as we go, and that's what keeps us excited about doing it."[RealVideo]

The Chemical Brothers will be appearing at Woodstock '99 this weekend alongside acts such as Limp Bizkit, Sugar Ray, Bush, Alanis Morissette, Live, the (aforementioned) Dave Matthews Band, and dozens of others. Tickets are still available for the event at www.ticketmaster.com. If you can't make it to Rome, New York, MTV News will be broadcasting live reports throughout the three-day festival as well as special editions of "MTV News 1515" all weekend.
