LL Cool J Surprises Z-Trip Fans

"If someone told me I'd be sharing a stage with a guy whose records I wore out as an up-and-coming DJ, I would have never believed 'em," says Z-Trip. "It's an honor to get down with an icon like LL Cool J. And besides, we're both from Queens."

Their collaboration was debuted on Saturday night to a packed audience during the last night of the SXSW Music Festival.

"I haven't performed live in a while & DJ Z-Trip is the only guy to get me back on the stage....Let's do this," says LL Cool J.
