Martin Garrix may be pumping out hits with Dua Lipa and Troye Sivan for the masses, but that's not to say he's lost his affection for the underground. The 21-year-old debuted his new alias, YTRAM, at his label STMPD's Tomorrowland showcase, where he played a deep/tech house set.

This new identity was not too difficult for Garrix fans to uncover. For starters, YTRAM is Marty spelled backwards. Moreover, while he kicked off the performance with a full face mask, he soon took it off, revealing his identity to the crowd. 

Watch YTRAM in action below: 

IT'S OFFICIAL! Ytram is Marty!
