 Chris has said the group was influenced by vocal groups like The Hi-Los (who performed in Greenwich Village frequently at the time) along with Peter, Paul and Mary and the counterpoint experiments of Benjamin Britten.Their trademark sound involved complex harmonies, jazz-like chord progressions, and off-beat time signatures, all products of Chris's classical training.The band released seven albums from 1967 to 1972, the first six on Enoch Light's Project 3 label and the last one, "There is a Song", on the Ambrotype label.
