After plenty of attention for her Twitter feuds and outspoken ways, Azealia Banks focuses back on the music, releasing a busy, percussion-heavy new song called “Yung Rapunxel.” This Lil Internet-produced track is the first single off the Harlem rapper’s debut, Broke With Expensive Taste, due out on Interscope later this year. “Yung Rapunxel” will be available on iTunes March 26.
