BYG Actuel was a French record label specializing in free jazz. The label also released a small number of non-jazz recordings by artists such as Musica Elettronica Viva, Freedom and Gong.

BYG Records was founded in March 1967 by Jean Georgakarakos, Jean-Luc Young and Fernand Boruso. The name of the label was formed from the initial letters of the founders' surnames. Karakos had previously established himself as a record distributor and importer, while Young worked for Barclay Records and Boruso for Saravah, the record label formed by filmmaker Claude Lelouch.

The label invited American free jazz musicians to Paris to record in the summer of 1969, a time when they were receiving little support or attention in the United States. Many of these musicians were already overseas at the time, having appeared at the Pan-African Music Festival in Algiers in July 1969. (Jazz photographer Jacques Bisceglia was largely responsible for connecting the label and musicians, and the "B" in BYG is often wrongly held to refer to Bisceglia.) The resulting albums are an important repository of free jazz recordings from the period.

Dewey Redman (born Walter Dewey Redman in Fort Worth, Texas, May 17, 1931; d. Brooklyn, New York September 2, 2006) was an American jazz saxophonist, known for performing free jazz as a bandleader, and with Ornette Coleman and Keith Jarrett.

Redman played mainly tenor saxophone, though he occasionally doubled on alto saxophone, played the Chinese suona (which he called a musette) and on rare occasions played the clarinet.

His son is saxophonist Joshua Redman.

After high school, Redman briefly enrolled in the electrical engineering program at the Tuskegee Institute in Alabama, but became disillusioned with the program and returned home to Texas. In 1953, Redman earned a Bachelors Degree in Industrial Arts from Prairie View Agricultural and Mechanical University. While at Prairie View, he switched from clarinet to alto saxophone, then, eventually, to tenor. Following his bachelor's degree, Redman served two-years in the US Army.

Upon his discharge from the Army, Redman began working on a master’s degree in education at the University of North Texas. While working on his degree, he taught music to fifth graders in Bastrop, Texas, and worked as a freelance saxophonist on nights and weekends around Austin, Texas. In 1957, Redman earned a Masters Degree in Education with a minor in Industrial Arts from the University of North Texas. While at North Texas, he did not enroll in any music classes.

Anthony Braxton (born June 4, 1945) is an American composer, saxophonist, clarinettist, flautist, pianist, and philosopher. Braxton has released well over 100 albums since the 1960s. Among the array of instruments he plays are the flute; the sopranino, soprano, C-melody, F mezzo-soprano, E-flat alto, baritone, bass, and contrabass saxophones; and the E-flat, B-flat, and contrabass clarinets.

Braxton studied philosophy at Roosevelt University. He has taught at Mills College and as of 2012 is Professor of Music at Wesleyan University in Middletown, Connecticut, teaching music composition, music history, and improvisation.

Early in his career, Braxton led a trio with violinist Leroy Jenkins and trumpeter Wadada Leo Smith and was involved with The Association for the Advancement of Creative Musicians, the "AACM", founded in Chicago, Braxton's birthplace.

In 1968, Braxton recorded the double LP For Alto. There had been occasional unaccompanied saxophone recordings previously (notably Coleman Hawkins' "Picasso"), but For Alto was the first full-length album for unaccompanied saxophone. The album's songs were dedicated to Cecil Taylor and John Cage, among others. The album influenced other artists like Steve Lacy (soprano sax) and George Lewis (trombone), who would go on to record their own acclaimed solo albums.

James Marcellus Arthur "Sunny" Murray (born September 21, 1936 in Idabel, Oklahoma) is one of the pioneers of the free jazz style of drumming.

Murray spent his youth in Philadelphia before moving to New York City where he began playing with Cecil Taylor: "We played for about a year, just practicing, studying - we went to workshops with Varèse, did a lot of creative things, just experimenting, without a job" He was featured on the influential 1962 concerts in Denmark released as Nefertiti the Beautiful One Has Come.

He was among the first to forgo the drummer's traditional role as timekeeper in favor of purely textural playing. "Murray's aim was to free the soloist completely from the restrictions of time, and to do this he set up a continual hailstorm of percussion ... continuous ringing stickwork on the edge of the cymbals, an irregular staccato barrage on the snare, spasmodic bass drum punctuation and constant, but not metronomic, use of the sock-cymbal"

After his period with Taylor's group, Murray's influence continued as a core part of Albert Ayler's trio who recorded Spiritual Unity: "Sunny Murray and Albert Ayler did not merely break through bar lines, they abolished them altogether."

Daevid Allen (born Christopher David Allen, 13 January 1938 in Melbourne, Australia), sometimes credited as Divided Alien, an Australian poet, guitarist, singer, composer and performance artist is co-founder of psychedelic rock groups Soft Machine (in the UK, 1966) and Gong (in France, 1970).

In 1960, inspired by the Beat Generation writers he had discovered whilst working in a Melbourne bookshop, Allen travelled to Paris where he stayed at the Beat Hotel, moving into a room that had recently been vacated by Allen Ginsberg and Peter Orlovsky. While selling the International Herald Tribune around Le Chat qui Peche and the Latin Quarter, he met Terry Riley and also gained free access to the jazz clubs in the area.

In 1961, Allen travelled to England, renting a room in Lydden near Dover and soon began to look for work as a musician. He first replied to a newspaper advertisement for a guitar player to join Dover-based group the Rolling Stones (no connection with the later famous band of that name) [1] who had lost singer/guitarist Neil Landon, but he did not join them. After meeting up with William S. Burroughs, and inspired by philosophies of Sun Ra, he formed the free jazz outfit, the Daevid Allen Trio, which included his landlord's son, 16-year old Robert Wyatt. They performed at Burroughs' theatre pieces based on the novel The Ticket That Exploded. In 1966, together with Kevin Ayers and Mike Ratledge, they formed the band Soft Machine, the name having come from the Burroughs novel The Soft Machine. Ayers and Wyatt had previously played in Wilde Flowers.
