Macklemore, Ryan Lewis' surprise performance on bus top

Macklemore & Ryan Lewis stunned the passengers of an NYC bus with a surprise performance of their hit single 'Can't Hold Us'.
The impromptu performance was a part of the Grammy's 'Music Unleashes Us' multi-platform ad campaign, which aims to capture people's natural, visceral and sometimes uncontrollable reactions to music, reported Ace Showbiz.
In the campaign video, the duo were seen wearing hoodies as they board a Bronx bus. After paying their fare, Lewis dropped his hoodie and turned on the music from his boombox while Macklemore walked down the bus aisle.
Some passengers were visibly confused when the rap duo began their impromptu performance, but they were later seen smiling, taking some videos or pictures with their phones, even clapping their hands and dancing along to the tune.

Macklemore & Ryan Lewis are nominated for seven awards at the upcoming Grammy Awards. They will compete against other musicians in categories that include Best New Artist, Song of the Year for their 'Same Love' and the prestigious Album of the Year for 'The Heist'.
They will also join artists like Taylor Swift, Daft Punk, Imagine Dragons and Kendrick Lamar to take the stage at the event as performers in the ceremony which will take place at Los Angeles' Staples Center on January 26.
