One of the most famous DJs in New York (and in the world for that matter), Junior has kept the records spinning for three decades now.

The son of a butcher, Donald Mattern was born in Lancaster, Pennsylvania-the heart of Amish country-and arrived in New York by bus in 1970. He enrolled at FIT and had plans to become a fashion designer; when that didn't pan out, he worked as a hairdresser and fashion illustrator. Having immersed himself in the club scene throughout the '70s, whiling away nights at David Mancuso's legendary Loft parties and Larry Levan's Paradise Garage during the golden age of dance music, Junior turned his attention to producing music. In the early days he collaborated with dance music pioneer Shep Pettibone, while also making a name for himself as a DJ. In 1989 he co-founded the Sound Factory and served as resident DJ throughout its early '90s heyday.

Junior spent the 1990s as one of the most in-demand record producers and remix masters, collaborating on tracks by the likes of Elton John, Cher, Prince, Cyndi Lauper, Janet Jackson, Annie Lennox, Paula Abdul, Justin Timberlake, and, weirdly, John Mellencamp. But he also kept up his DJ career. Although Sound Factory closed in 1995, Junior went on to man the turntables at Peter Gatien's Tunnel and Palladium, before returning to the former Sound Factory space when it reopened as Twilo in 1997. Since the shuttering of Twilo in 2000, he's been a regular at Pacha, Exit, and Spirit-the space that once housed Twilo-and spends many days year on the road, bringing his music to party-loving people in Miami, Ibiza and major Euro capitals.
