"John Russell got his first guitar in 1965 while living in Kent and began to play in and around London from 1971 onwards. An early involvement with the emerging free improvisation scene (from 1972) followed, seeing him play in such places as The Little Theatre Club, Ronnie Scott's, The Institute of Contemporary Arts, The Musicians' Co-Op and the London Musicians' Collective. From 1974 his work extended into teaching, broadcasts (radio and television) and touring in the United Kingdom and, ever extensively, in other countries around the world . He has played with many of the world's leading improvisers and his work can be heard on over 50 CDs and albums. In 1981, he founded QUAQUA, a large bank of improvisers put together in different combinations for specific projects and, in 1991, he started MOPOMOSO which has become the UK's longest running concert series featuring mainly improvised music."

"Raymond 'Ray' Russell (born 4 April 1947) is an English session musician who is primarily a guitarist. He is also renowned as a record producer and composer.

In 1973 he was a member of the band Mouse, which released a progressive rock album entitled Lady Killer for the Sovereign record label. His TV compositions have included A Touch of Frost, Bergerac, Plain Jane, A Bit of a Do, Rich Tea and Sympathy, The Inspector Alleyn Mysteries, Dangerfield and Grafters, as well as many other British and American television programmes. He also played in the DVD Simon Phillips Returns with Simon Phillips and Anthony Jackson.

With colleagues Mo Foster and Ralph Salmins, Russell gives musical seminars at UK educational establishments.

In 2008 Russell, drummer Ralph Salmins, and sound engineer Rik Walton created Made Up Music, a music library that distributes music on its web site and by sending portable hard drives to music editors. The company sells music by Russell, Mo Foster, Steve Donnelly, and Simon Eyre.

In March 2020 Russell featured on an episode of the BBC Television programme Antiques Roadshow, in which his fretless six-string electric guitar, made by Bartell and gifted to him by George Harrison, having originally belonged to John Lennon, was valued at £300,000-£400,000."

"Henry Kaiser (born September 19, 1952) is an American guitarist and composer, known as an idiosyncratic soloist, a sideman, an ethnomusicologist, and a film score composer. Recording and performing prolifically in many styles of music, Kaiser is a fixture on the San Francisco Bay Area music scene. He is considered a member of the "second generation" of American free improvisers. He is married to Canadian artist Brandy Gale.

In 1977, Kaiser founded Metalanguage Records with Larry Ochs (Rova Saxophone Quartet) and Greg Goodman. In 1979 he recorded With Friends Like These with Fred Frith, a collaboration that lasted for over 20 years. In 1983 they recorded Who Needs Enemies, and in 1987 the compilation album With Enemies Like These, Who Needs Friends? They joined with fellow experimental musicians John French, and English folk-rocker Richard Thompson to form French Frith Kaiser Thompson for two eclectic albums, Live, Love, Larf & Loaf (1987) and Invisible Means (1990). In 1999 Frith and Kaiser released Friends and Enemies, a compilation of their two Metalanguage albums along with additional material from 1984 and 1999.

In 1991, Kaiser went to Madagascar with guitarist David Lindley. They recorded roots music with Malagasy musicians and discovered music that, he says, "changed us radically and permanently". Three volumes of this music were released by Shanachie under the title A World Out of Time. In 1994 he made a similar trip to Norway, again with Lindley, recording music that was released as Sweet Sunny North (2 volumes, 1994 and 1996).

Since 1998, Kaiser has been collaborating with trumpeter Wadada Leo Smith in the "Yo Miles!" project, releasing a series of tributes to Miles Davis's 1970s electric music. This shifting aggregation has included musicians from the worlds of rock (guitarists Nels Cline, Mike Keneally and Chris Muir, drummer Steve Smith), jazz (saxophonists Greg Osby and John Tchicai), avant-garde (keyboardist John Medeski, guitarist Elliott Sharp), and Indian classical music (tabla player Zakir Hussain).

Kaiser has appeared on more than 250 albums and scored dozens of TV shows and films, including Werner Herzog's Encounters at the End of the World (2007). He was given a Grammy Award for his work on the Beautiful Dreamer tribute to Stephen Foster.

In 2001, Kaiser spent two and a half months in Antarctica on a National Science Foundation Antarctic Artists and Writers Program grant. He has subsequently returned for nine more visits to work as a research diver. His underwater camera work was featured in two Herzog films, The Wild Blue Yonder (2005) and Encounters at the End of the World (2007), which he also produced, and for which he and Lindley composed the score. Kaiser served as music producer for Herzog's Grizzly Man (2005). He was nominated for an Academy Award for his work as a producer on Encounters at the End of the World."
