Fans of the mysterious Jai Paul and his seldom but exceptional singles will delight in knowing there's another way to hear more. Turns out, Jai has a brother named Anup (who goes by AK) and his talents are equally outstanding. With an ultra-sleek, hip-hop-infused approach to producing, it comes as no surprise to learn that AK has collaborated on albums with Jessie Ware and Big Boi, and has this week released a track with East London singer Nao on "So Good." The song lives up to its name by combining Nao's sensual, high-pitched vocals with a booty-shaking beat. Consider this one a musical aphrodisiac.
