FKA twigs, the 26-year-old singer and producer born Tahliah Barnett, paces around her Manhattan hotel room on an evening in late June, impatiently refreshing her email on her iPhone. The Londoner is waiting for Nabil Elderkin, the in-demand director behind videos like Frank Ocean’s “Pyramids” and Nicki Minaj’s “Lookin Ass”, to send her the final cut of the visual for her new single “Two Weeks”. While recording her upcoming debut album, LP1, Barnett inched toward artistic autonomy, teaching herself how to use the software necessary to produce or co-produce many of her songs (alongside bold names including Adele collaborator Paul Epworth and sometime Drake hook man Sampha). She paints herself as a goal-oriented perfectionist. “I have to learn everything there is to learn,” she says at one point. So she seems a bit unnerved anticipating Elderkin’s edit, tripping up when she tries to describe the video’s concept. “It’s really complicated,” she concedes.
