The Grammy nominated stars give a live rendition of their track 'Can't Hold Us' to commuters.
Macklemore & Ryan Lewis performed an impromptu gig on a New York City bus this week.
The pair walk onto the packed bus looking inconspicuous before Ryan gets the music going and Macklemore unleashes his rap skills in front of the shocked passengers.
He soon gets them involved and even starts playing around with some kitchen roll – even the driver is seen clapping along.
The video was released last night (14th January), shortly after it was revealed the pair had joined the performers line-up for the Grammy Awards 2014.
They are also shortlisted for seven prizes on the night – which takes place live from the Staples Center in LA on 26th January.
