Last week, Mac Miller joined music guest Ariana Grande on Late Night with Jimmy Fallon for a performance of their collabo song “The Way.” That performance aired, this one, however, did not. Before the show started, Mac Miller hooked up with The Roots to perform Mac’s song “S.D.S.” to warm up the crowd. As I typically feel, The Rootsified live version of the song >> the original version. Check the web exclusive performance, below. Mac’s LP, Watching Movies With The Sound Off, is out now.
