First released in 1965, "Frost & Fire", a calendar of ritual and magical songs was the first album from the then new group on the folk scene. Originally from Hull, two sisters, their brother and cousin had been singing family songs all their lives and as a new folk group had been attracting attention for their powerful and exciting performances. They were taken into the studio by Bill Leader to record an album for Topic Records and what came out of the sessions was incredible. "Frost & Fire" was essentially a concept album, the songs following the passage of the year. It's effect was seismic, standing the folk scene on it's head and influencing not just folkies but the ever growing and eclectic rock scene as well, particularly Traffic whose magnificent "John Barleycorn Must Die" came directly from "Frost & Fire".
