Though musical mash-ups are the hot trend, Jermaine Dupri doesn't necessarily see the blending of two songs to create another as something new.

"I've always mixed different music with other music (as a DJ)," said the top producer/performer.< /p>

Now, Dupri will do it once again as musical director for the Aug. 19 AmsterJam concert in New York City, where acts such as the Foo Fighters, LL Cool J, Busta Rhymes and Tom Petty will blend their music with that of other acts live onstage.

"What you hear will be my creation basically ... or how I think the mash-ups should go," said Dupri in an interview with The Associated Press this week. "I'm kind of visualizing this from a DJ perspective."

Dupri, 33, will decide how the artists' songs will be blended.

"LL Cool J and (reggaeton star) Tego (Calderon), that's going to be a hard one," he said. "As the music director, I have to step up to the plate."

This is the second year for AmsterJam, an all-day festival.
