The J&R MusicFest 2010 took place this past weekend with a free concert by Roc Nation’s own J. Cole & Alexis Jordan, alongside Marsha Ambrosius. Newcomer Alexis Jordan opened up the show with aÂ dopeÂ acapella of Rihanna’s “Umbrella” (which showcased her silky vocal chops), and her dance hit “Happiness”. J. Cole had the NYC crowd in an uproar as he rapped some of his now classic mixtape joints & his hit “Who Dat”, along with the summerÂ jointÂ “I Want You” ft. Miguel. I missed Marsha’s set, but I heard she ended the show like nobody else could! Friend to the site, Karina Pasian was spotted enjoying the festivities as well!
