You have to respect artists hustling at the coffee shop. Here, a guy was performing Matisyahu's hit song "One Day," and little did he know, the reggae singer was actually at this coffeeshop and jumped in to perform with him. The singer was impressed by this strangers skills and had to be convinved that his new duet partner was actually Matisyahu. Really cool live performance, Matis seems like a genuine dude. Would love to hang with him. Check out the video below.
