In the '60s and '70s, much (if not most) contemporary improvisation was jazz-based. That began to change in the '80s, when a significant number of rock musicians began exploring the possibilities of free improvisation and new classical forms.
Fred Frith is one of the more prominent. Co-founder of the underground British band
Henry Cow in 1968, composer/improviser/guitarist
Frith moved to the U.S. in the late '70s, where he began associations with such New York-based experimental musicians as cellist
Tom Cora, harpist
Zeena Parkins, saxophonist
John Zorn, and percussionist
Ikue Mori.
Frith lived in New York for 14 years; some of his well-known ventures in that time included
Massacre (with
Bill Laswell and
Fred Maher),
Skeleton Crew (with
Cora and
Parkins), and his sextet Keep the Dog. In the '80s,
Frith's compositional activities increased; he began writing for dance, film, and theater, and for such ensembles as
the Rova Saxophone Quartet, Ensemble Moderne,
Asko Ensemble, and his own Guitar Quartet. Primarily known as an improvising guitarist,
Frith has also performed on bass (with
Zorn's
Naked City) and violin (with
Lars Hollmer's Looping Home Orchestra).
Frith has played on albums by
the Residents,
Brian Eno,
Amy Denio, and
René Lussier, to name just a few.
Frith was the subject of Step Across the Border, a documentary film by
Nicolas Humbert and Werner Penzels. By 2000,
Frith was a professor of composition at Mills College in Oakland, CA, and continued to release a bevy of albums including
Eleventh Hour in 2005 and
Sugar Factory in 2007. ~ Chris Kelsey, All Music Guide
