On Saturday the WOO HAH! Festival took place in Tilburg and A$AP Ferg had a very special suprise during his performance. Near the end of his show he brought out A$AP Rocky to perform Lord Pretty Flacko Jodye 2, Work, Shabba & New Level. As if Flacko’s guest appearance wasn’t epic enough Tyler, The Creator, ScHoolboy Q & Young Thug also got on stage. This was a legendary hip hop concert moment to say the least. Check it out below.
