Because performing in a stationary room is way too easy, we present the Popdust Party Bus, where our favorite pop stars play their hits in front of a handful of lucky fans on a tricked-out mini-bus.

Today on the Party Bus... Karmin, the once-viral rap cover duo currently scaling the highest heights of the Top 40 with their infectious pop breakthrough single "Brokenhearted." Amy and Nick perform their hit single on our mobile venue, as well as three other songs: "Hello," "Crash Your Party," and the cover that started it all for the Boston duo, Chris Brown's "Look At Me Now." Watch and listen, and feel free to rap along at home.
