Pittsburgh rapper Frzy unofficially breaks Guinness World Record for longest freestyle rap

"It's something that he's been wanting to do, to put Pittsburgh on the map for his music, and in addition, during the 31 hours, he is raising money for Music Cares," said event organizer John Chamberlin.

Music Cares helps musicians in need.

All of the videos and data collected will now be sent to the Guinness officials for evaluation and confirmation.
