Coachella is notorious for surprise guest appearances, however we may have just seen one of he most random and unexpected surprises in the festival's history.

Helmet-weilding electronic and EDM artist Marshmello shocked everyone by bringing out Travis Barker to help him perform his huge 2016 hit Alone.

But they weren't done there, with the Blink-182 drummer and Marshmello engaging in an epic drum battle face-off, accompanied by a full-on Mortal Kombat backdrop.

Check out the wonderfully random shenanigans below.
