Susan Dimiti "Suzy" Williams is an American singer-songwriter. She became well known through the musical duo Stormin’ Norman & Suzy. Williams has performed at venues ranging from Carnegie Hall and Lincoln Center to the Hotel Palmas in the Canary Islands, and on network television and film. She has been reviewed in publications including Rolling Stone, The New York Times, Cosmopolitan, and Los Angeles Magazine. Her singing was referred to in Rolling Stone as a "mixture of Bessie Smith, Sophie Tucker, and perhaps a trace of Janis Joplin".

Williams was born in Oakland, California, and raised in Gridley, California by her mother, Barbara Artie King Liggett, an artist, pianist, and torch singer. Her father, David P. Williams, was a social worker and organizer who worked with Cesar Chavez and Ralph Nader, and also performed professionally as a comedian in San Francisco in the early 1950s.

Williams started singing professionally following high school, mainly influenced by Harry Nilsson, Randy Newman, and especially Bessie Smith. Her later influences include singers June Christy and Anita O'Day.

At eighteen years old, Williams moved to Boston, Massachusetts and met "Stormin’ Norman" Zamcheck, a composer and boogie-woogie piano player with a degree in literature from Yale University. As a musical duo, they created a "rag'n'roll" style, combining boogie-woogie, blues, rock, and jazz. Together they toured the U.S. east coast for 12 years, eventually playing Carnegie Hall and receiving favorable reviews from the New York Times, Rolling Stone, and Cosmopolitan. Stormin’ Norman & Suzy, primarily managed by Bruce Hambro, were signed with Polydor Records in 1977 by co-manager Sid Bernstein.

Williams's singing in Stormin’ Norman & Suzy has been called a "mixture of Bessie Smith, Sophie Tucker, and perhaps a trace of Janis Joplin". Jazz musicians Horace Silver, Roosevelt Sykes, and Hadda Brooks have complimented her. Jazz pianist and composer Eubie Blake paid Williams an inspiring compliment in a handwritten letter: “I heard alot [sic] of white women try to imitate negroid singing, but you are the only one who has it down pat."

Guitarists who have played with Stormin' Norman & Suzy include Marc Ribot, Mark Shulman, and Jeff Golub. Stormin’ Norman & Suzy was the house band for three years at New York City's Tramps night club, and have appeared on network television shows including Gabe Kaplan Presents the Future Stars and Don Kirshner's Rock Concert. The band has also performed with the Pilobolus Dance Company, who choreographed a dance based on Williams’ movements. The band embarked on an international tour in 1979. In 1983, they had a two-month residency at the Hotel Palmas in the Canary Islands. Stormin' Norman & Suzy continue to tour together occasionally.

Williams also worked independently singing with pop singer, songwriter, and actor David Johansen, a.k.a. Buster Poindexter of the New York Dolls. In the 1980s she starred on the off-Broadway stage with Sam Rockwell and Natasha Schulman in Bruno's Donuts: Dementos, written by Marc Shaiman and Robert I. Rubinsky; and in Dames in Hoagland, with Cathy Chamberlain and produced by Jerry Wexler.

In 1986 Williams formed a duo with her then-husband Bill Burnett as The Boners and performed regularly at Heather Woodbury's Cafe Bustelo in New York City. They also played with They Might Be Giants in Williamsburg, Brooklyn, New York City. Williams and Burnett's melodic neo-cabaret folk-rock style culminated in "Our Show" held at the West Beth Theater and a local Public Access Cable TV comedy-music show "The Boners Show". Their radio show for kids, "The Flying Kitchen", aired in New York City. They toured with James Sewall and Sally Rousse in The New York Song and Dance Ensemble, performing at Lincoln Center. They have played the Sweet Chariot Music and Arts Festival in Swans Island, Maine every year since 1986.
