If you don’t know by now, Martin Garrix is an EDM superstar. Breaking into the scene with his huge track ‘Animals’, Martin Garrix is not only one of the youngest but also one of the most talented names in electronic music. If Garrix doesn’t draw one of the biggest crowds at Summerfest’s grounds stages, we will definitely be surprised. Let’s just hope that even the World’s Largest Music Festival has the capacity for the numbers that Garrix will draw in on June 29th. A Martin Garrix concert for just $13? You won’t find a better deal in live music.
