"I can rap over opera music if you gave it to me," London-bred rapper Dizzee Rascal boasted to the BoomBox during a taping of an exclusive 16 Bars freestyle segment in our New York studio. Dizzee waltzed into our New York studio, stepped up to the microphone and delivered pure fire over Lil Wayne's 'Fireman,' no pun intended.

A man of few words when confronted by the media, the British rapper -- known for meshing his self-produced basement beats with funky eclectic samples to create the rugged 'Dirtee Stank' sound -- felt right at home in front of the microphone, so much so that he flowed for almost five minutes with no hesitation.
