550 Music

550 Music (originally known as Sony 550 Music) was a record label and subsidiary imprint of Sony Music, operating through Sony Music's Epic Records division. The name was inspired by the address of then Sony Tower at 550 Madison Avenue in New York City. From its launch in September or October 1993, Polly Anthony served as its general manager. Local rock band Eve's Plum was its first signing, among six more acts.
