Well, it is finally here! Connecticut native DJ/producer, Audien, finally released his summer smasher, "Serotonin," featuring no other than Matthew Koma. After originally previewing this tune last month via his premiere on Danny Howard's BBC Radio 1 Show, the progressive house tune is now out on Beatport! Audien still give us that signature melodic beat, while providing a variety of zestful drops, incorporating Koma's vocals masterfully over his melodic beats. Enjoy below!
