In preparation for the release of his forthcoming third studio album, Lasers, Lupe Fiasco—accompanied by The Robert Glasper Experiment—took to The Blue Note Jazz Club in New York City for a jam-packed intimate show. The Chicago-bred MC was joined by surprise guests Kanye West and Mos Def who took to the mic for a 7-minute freestyle. Listen to Chicago and New York's finest kick it impromptu style.
