If there’s any time to debut new music, it’s at a festival like Ultra… and while young Dutch phenom Martin Garrix was in Croatia for Ultra Europe, he did just that. Throughout his full set, he dropped four IDs on the crowd, including one toward the end that was revealed to be a collaboration with longtime friend Justin Mylo.

Check out a clip of his set from the festival below, recorded via the live stream. Check out the full tracklist for his set here.
