Macklemore decided to remind us how cool he and his pal Ryan Lewis are by surprising a bus full of NYC commuters with an impromptu performance of 'Can't Hold Us.' The stunt was part of a promotional campaign for the 2014 Grammy Awards, set to air Sunday, January 26.

Macklemore and Ryan Lewis are also nominated for seven Grammys, including Best New Artist, and Best Rap Album and Album of the Year for 'The Heist.'

Too bad they don't give out Grammy's for awesome free surprise bus concerts.
