Fred Frith is a songwriter, composer, multi-instrumentalist (bass, keyboards, violin) and an improviser performing mostly on various permutations of the electric and acoustic guitar. Occasionally he uses crude home-made string instruments of his own invention.
He learned how to compose in rock bands, starting with Henry Cow in 1968. This meant writing for and with people that he knew, and then arriving at the final result through a collective rehearsal process.
