Tyson took up folk music in his 20s while convalescing from a rodeo injury, and teamed up with Sylvia Fricker after moving to Toronto in the late '50s. In 1960, they moved to New York, where they were signed by Albert Grossman, famous for managing Bob Dylan and Peter, Paul, and Mary. Their self-titled debut (1962) began a successful series of recordings for Vanguard, on which they helped expand the range of folk by adding bass (sometimes played by Spike Lee's father Bill) and mandolin to Ian's guitar and Sylvia's autoharp. Just as crucially, they ranged far afield for their repertoire, which encompassed not just traditional folk ballads, but bluegrass, country, spirituals, blues, hillbilly, gospel, and French-Canadian songs.
Ian & Sylvia were among the first to cover songs by Dylan, Lightfoot, Joni Mitchell, and Phil Ochs, and also began writing material of their own. Although original compositions were never at the forefront of their early LPs, a couple of them would become very influential indeed. Ian's "Four Strong Winds" would be covered by the Searchers and (in the '70s) Neil Young, and Sylvia's "You Were on My Mind," given a far poppier treatment by the We Five, became one of the first big folk-rock hits.
By 1966, Ian & Sylvia had started to rely primarily on original material, and begun to use electric instruments. While some of these tracks were outstanding, generally their folk-rock lacked the focus and consistency of their acoustic recordings. In the late '60s, they would take stabs at country-rock and straight country music, even hooking up with young producer Todd Rundgren for the 1970 album Great Speckled Bird. The quality of their records, and the size of their audience, declined steadily after they ended their association with Vanguard in 1967. In the '70s, they split up, professionally and personally (they had married in 1964). Both have since pursued solo careers: Ian's was far more successful, as he moved into country music, recording albums of songs with cowboy and rodeo themes that received much popular and critical acclaim in Canada. ~ Richie Unterberger
