Two years ago Macklemore & Ryan Lewis were making the small theatre circuit performing songs off of their latest album, “The Heist.” Now they’re rap megastars and getting set to perform a short set for The Grammys.

What better way to highlight both Macklemore & Ryan Lewis’ grassroots career-building and promote The Grammys too than to have them perform on a bus?

The surprise performance is pretty sweet (if not probably a little staged), but they aren’t the first music superstars to ambush folks with an impromptu performance. In fact, it happens fairly frequently. So look around and maybe one of these artists (or many others) will show up in your world.
