Lupe Fiasco was in NYC this weekend to perform a quadruplet of shows with noted jazz musician, Robert Glasper and his band, The Robert Glasper Experience. To cap off one of the Saturday night shows, Lupe was joined by Kanye West and Mos Def, who participated in a true freestyle session for 30 minutes backed by Robert Glasper and his band. The trio treated the audience to an intimate performance featuring freestyles, new verses, and classic favorites, as Mos Def also performed “Umi Says”. AllTheWayLive was present, and recorded the entire performance, which you can now download by right-clicking here.
