Bill Janovitz (born June 3, 1966) is an American musician and writer. He was the singer, guitarist, and songwriter of alternative rock band Buffalo Tom, and has also released three solo albums. Janovitz has written extensively for Allmusic, authored the Exile on Main St. book for the 33⅓ series, and contributed to BostonMagazine.com, the Boston Phoenix, and Post Road magazine.
After enrolling at the University of Massachusetts Amherst, Janovitz formed Buffalo Tom with fellow students Chris Colbourn and Tom Maginnis. A friendship with J. Mascis of Dinosaur Jr. helped the band's career to take off, with Mascis producing the band's first two albums to critical acclaim. Commercial success followed with their subsequent records as the band developed a fanbase both at home and abroad.
In 1997, Janovitz released the solo album Lonesome Billy, with help from Joey Burns and John Convertino of Giant Sand and Calexico, utilising unused Buffalo Tom songs to form the bulk of the album.
