Last night, Atlanta was in the building full force for the final installment of FADER and Vitaminwater's #uncapped concert series. B.o.B took the stage at The General Society Library with a performance of "Strange Clouds." Then, to the crowd's surprise, he was joined by fellow ATLien Big Boi during his performance of "Nothing On You" and "Shoes For Running." Then, Future added to the stream of surprises by hitting the stage to perform "Ready," "Bugatti" and "Honest." Watch the memorable performance above.
