In 1988 they won the Grammy for Best New Age Performance for Folksongs for a Nuclear Village. In 1992 they were nominated for the Grammy for Esperanto. The group formed in 1972 and disbanded after 1995 when Lyricon player and leader Chuck Greenberg died of a heart attack. Having lost their signature sound, Shadowfax's members went on to other projects.
