Despite his success, Macklemore & Ryan Lewis takes it back a bit and gives back to the people. The pair recently surprised a bus full of New Yorkers with an impromptu performance in a promo for the Grammys’ “Music Unleashes” campaign.

Lewis clutched a boombox, and boarded the bus and immediately begin performing their hit “Can’t Hold Us” for commuters, who weren’t sure what was happening.

Macklemore & Ryan Lewis are among the performers for 56th Annual Grammy Awards, set for Jan. 26th.
