Formed in England in 1980 by saxophonist Evan Parker (born on April 4, 1944 in Bristol, England), double bassist Barry Guy (born on April 22, 1947 in London, England), and drummer Paul Lytton (born on March 8, 1947 in London, England), the improvisational jazz trio is known simply by their names Evan Parker/Barry Guy/Paul Lytton. Each of the three musicians had already built up their legendary jazz careers in the 1960s and 1970s, recording with other artists as well as crossing paths in the studio and on the road. Evan Parker and Paul Lytton had met in 1967 at a music festival in Birmingham, England where they were both playing in different bands. The two of them eventually recorded the album Collective Calls (Urban) (Two Microphones) in 1972, setting the scene for what was to come in the future. Over the next few years, Evan Parker, Barry Guy, and Paul Lytton played together in different combinations and permutations including Barry Guy’s London Jazz Composers Orchestra. Their debut album as a trio, Tracks, was released in 1983. While the three musicians continued to work on projects outside of the trio, they continued to release a series of albums including Imaginary Values (1994), At the Vortex (1996), Zafiro (2006), and Concert in Vilnius (2019).
