Youngster DJ Martin Garrix teamed up with Usher to produce his next killer track, Don't Look Down. It is not quite like the Martin Garrix we know. After Animals - his flagship production thus far - he simply continued producing one big room house track after another. He is having a great time obviously, entertaining partying crowds all over the world. But with Don't Look Down - and maybe even more so with the track Hidden Voices - Martin Garrix is venturing into new territory.
