Question: Did the group that Stinson founded have more than three members? Passage:Gregory E. Stinson, better known as G. E. Stinson (born in Kingfisher, Oklahoma), is an American guitarist and founding member of new age/electronic musical group Shadowfax. Inspired by blues masters such as Bo Diddley and Muddy Waters, Stinson experimented with blues, jazz and other musical genres before co-founding Shadowfax in 1974. He remained with the band for six albums. He departed Shadowfax after recording The Odd Get Even (1989), entering the Los Angeles underground music community to refine his 'extended technique' and 'frequency manipulation'. Since then he has worked with a number of musicians on various projects, including Napalm Quartet, Splinter Group, Stinkbug, Metalworkers, Alex De Grassi, Devin Sarno and others. In 2000, he collaborated with drummer Gregg Bendian, violinist Jeff Gauthier, and bassist Steuart Liebig on an album of collective improvisational pieces recorded live in the studio, entitled Bone Structure. Released in 2003, it was given four stars by Jim Andrews in DownBeat magazine.
