Just a few days ago (July 21st), while walking the dark streets of Union Square, New York City... Kendrick Lamar & Co. just so happened to run into one Johnathan Rivera. Lamar then proceeded to jump in on Rivera's impromptu busked [Classical] riffs - Flipping a raw, endearing freestyle over top. The result has been dubbed "Violin Freestyle" and is indeed an extremely original, DIY experience. Pay attention @ the end of the video, as Kendrick and Johnathan [seemingly] trade contact info... So, stay tuned for more recordings on the horizon from the FRESH pair!
