The Holy Modal Rounders were an American folk music duo from the Lower East Side of New York City which started in the early 1960s, consisting of Peter Stampfel and Steve Weber. Their unique blend of folk music revival and psychedelia gave them a cult-like following from the late 1960s into the 1970s. For a time the band also featured prolific and famous playwright and actor, Sam Shepard.

Stampfel also formed the short-lived (1975-77) Unholy Modal Rounders with Kirby Pines, Charlie Messing, Jeff Berman and Paul Presti. The Unholy Modal Rounders were part of the collaboration, Have Moicy!, along with Michael Hurley and Jeffrey Frederick and the Clamtones. Read more on Last.fm.
