Jason Evigan’s years as the frontman for alt-rockers After Midnight Project helped refine his ear for melody. It’s something he brings to the studio as one of today’s most sought-after songwriter/producers, too, giving uptempo tracks such as Jason Derulo’s “Talk Dirty” and Pitbull’s “Fun” a slick, soulful sensuality. His towering anthems, like Nick Jonas’ “Chains” and Maroon 5’s “Girls like You (ft. Cardi B),” convey a sense of joyful escapism. And the house-meets-indie pop fusion of RÜFÜS DU SOL's “Underwater” is driving and hypnotic, proof that his eclectic collaborations always keep you guessing.
