Buffalo Tom is an alternative rock band from Boston, Massachusetts, formed in the 1980s. Its principal members are guitarist Bill Janovitz, bassist Chris Colbourn, and drummer Tom Maginnis. The band's name is derived from the band Buffalo Springfield and the first name of the drummer, who is the shyest of the three. Combining the two is something of a joke among the members. Dinosaur Jr guitarist/frontman J Mascis assisted with the production on the band's first two albums. J Mascis also played lead guitar on the song "Impossible" from Buffalo Tom's self-titled debut. Based on Mascis' input, early on the band was sometimes called Dinosaur Jr, Jr.
