52-Year-Old Kurtis Blow UNREAL Breakdancing Moves ... On Tape!

It's been 30 years since he released "The Breaks," but 52-year-old Kurtis Blow can STILL bust out some of the nastiest moves ever ... and TMZ has obtained the incredible footage.

Kurtis -- joined by fellow hip hop legends Doug E. Fresh, Grandmaster Caz and Grandmaster Dee -- performed this week at the Affiliate Ball at the Latin Quarter in NYC (the same place Plaxico Burress shot himself in the leg back 2008) ... and they set the stage on FIRE with some classic old school.

At Kurtis' age, you'd think the only break he'd be worried about is his hip. Clearly, that ain't the case.
