This year during Miami Music Week, David Guetta announced that he’d be starting a new record imprint for electronic music, straying from his recent pop comfort zone. Jack Back Records’ first single release is a collaboration with Nicky Romero & Guetta himself titled “Metropolis.” The track features two very different drops. This first half of the song is centered around a very unique bass wobble, eliciting an irrepressible urge to dance. By the second half, the wobble slowly fades out while piano chords begin to fade in. Next thing you know, the whole crowd is jumping with their hands in the air. You need to hear it to believe it.
