Thomas Alan Waits (born December 7, 1949) is an American musician, composer, songwriter and actor. His lyrics often focus on the underbelly of society and are delivered in his trademark deep, gravelly voice. He worked primarily in jazz during the 1970s, but his music since the 1980s has reflected greater influence from blues, rock, vaudeville, and experimental genres.

Waits was born and raised in a middle-class family in Whittier, California. Inspired by the work of Bob Dylan and the Beat Generation, he began singing on the San Diego folk music circuit as a young boy. He relocated to Los Angeles in 1972, where he worked as a songwriter before signing a recording contract with Asylum Records. His first albums were the jazz-oriented Closing Time (1973) and The Heart of Saturday Night (1974), which reflected his lyrical interest in nightlife, poverty, and criminality. He repeatedly toured the United States, Europe, and Japan, and attracted greater critical recognition and commercial success with Small Change (1976), Blue Valentine (1978), and Heartattack and Vine (1980). He produced the soundtrack for Francis Ford Coppola's film One from the Heart (1981), and subsequently made cameo appearances in several Coppola films.
