"Joe McPhee, born November 3,1939 in Miami, Florida, USA, is a multi-instrumentalist, composer, improviser, conceptualist and theoretician. He began playing the trumpet at age eight, taught by his father, himself a trumpet player. He continued on that instrument through his formative school years and later in a U.S. Army band stationed in Germany, at which time he was introduced to performing traditional jazz. Clifford Thornton's Freedom and Unity, released in 1969 on the Third World label, is the first recording on which he appears as a side man. In 1968, inspired by the music of Albert Ayler, he took up the saxophone and began an active involvement in both acoustic and electronic music.

His first recordings as leader appeared on the CJ Records label, founded in 1969 by painter Craig Johnson. These include Underground Railroad by the Joe McPhee Quartet (1969), Nation Time (1970), Trinity (1971) and Pieces of Light (1974). In 1975, Swiss entrepreneur Werner X. Uehlinger release Black Magic Man by McPhee, on what was to become Hat Hut Records.

In 1981, he met composer, accordionist, performer, and educator Pauline Oliveros, whose theories of "deep listening" strengthened his interests in extended instrumental and electronic techniques. he also discovered Edward de Bono's book Lateral Thinking: A Textbook of Creativity, which presents concepts for solving problems by "disrupting an apparent sequence and arriving at the solution from another angle." de Bono's theories inspired McPhee to apply this "sideways thinking" to his own work in creative improvisation, resulting in the concept of "Po Music." McPhee describes "Po Music" as a "process of provocation" (Po is a language indicator to show that provocation is being used) to "move from one fixed set of ideas in an attempt to discover new ones." He concludes, "It is a Positive, Possible, Poetic Hypothesis." The results of this application of Po principles to creative improvisation can be heard on several Hat Art recordings, including Topology, Linear B, and Oleo & a Future Retrospective.

In 1997, McPhee discovered two like-minded improvisers in bassist Dominic Duval and drummer Jay Rosen. The trio premiered at the Vision Jazz Festival in 1998 but the concert went unnoticed by the press. McPhee, Duval, and Rosen therefore decided that an apt title for the group would be Trio X. In 2004 he created Survival Unit III with Fred Lonberg-Holm and Michael Zerang to expand his musical horizons and with a career spanning nearly 50 years and over 100 recordings, he continues to tour internationally, forge new connections while reaching for music's outer limits."

"Lisle Ellis, (born November 17, 1951) is a Canadian jazz bassist and composer who is known for his improvisational style and use of electronics.

Ellis was born in Campbell River, British Columbia. Ellis began playing electric bass in his teens and worked professionally from an early age in numerous environments including studios, radio & TV shows, and strip clubs. He was born Lyle Steve Lansall, but used his initials L. S. as his stage name Ellis; he also used the name L. S. Lansall-Ellis professionally.

Ellis studied at the Vancouver Academy of Music with Walter Robertson and attended Douglas College in Vancouver. He later studied at the Creative Music Studio in New York City from 1975-1979.

Ellis lived in Toronto, Ontario, Canada from 1982 until 1983 and then Montreal, Quebec, Canada from 1983 until 1992. In 1986 Ellis was the first recipient of Canada's Fred Stone Award, given annually to a musician for integrity and innovation. In the early 1980s in Vancouver, and the late 80's in Montreal, Ellis was a conspicuous activator of musician alliance organizations, performance venues, and concert series presentations. One collective in particular, Vancouver's New Orchestra Workshop, is still active nearly thirty years later.

After moving to the United States in 1992, he settled in San Francisco, working with Glenn Spearman from 1992 until 2001. He lived in San Diego from 2001Ð2005 and New York City from 2005 to the present. In 1994, he was a member of the Cecil Taylor band for a brief tour of California.

Ellis's discography includes performances with Peter Brštzmann, Andrew Cyrille, Joe McPhee, Dave Douglas, Glenn Spearman and about 40 recordings for Music & Arts, Black Saint, DIW, Hat Art, New World, and Victo. His 1989 album, Kaleidoscopes: The Ornette Coleman Songbook, with pianist Paul Plimley, was given five stars in Down Beat magazine.

Since the late 1990s, Ellis has been primarily focused on developing an electro-acoustic interface he calls "bass & circuitry". By 2008, with the completion of a template for this interface Ellis turned his attention back to acoustic music projects with an emphasis on jazz based improvisation and to finding a balance between his electronic and acoustic music interests.

Central to Ellis's music, and a vehicle for both his electronic and acoustic experiments, has been his long standing trio with Larry Ochs and Donald Robinson called What We Live. Di Terra, an Italy-based trio with Alberto Braida (piano), and Fabrizio Spera (drums), has been an exclusively acoustic music vehicle for Ellis. His experimental trio Audible Means with Ellery Eskelin (saxophone), and Erik Deutsch (keyboards), was active on the New York scene in 2006 and 2007 and was a focal point for Ellis's bass & circuitry explorations. Since his arrival in New York, collaborations and interactions with composer/electronic musician Tom Hamilton have also been important to Ellis's work in electronic music."

"Paul (Horace) Plimley (born 16 March 1953 in Vancouver, British Columbia) is a free jazz pianist and vibraphonist. He is one of the doyens of the Canadian jazz avant-garde, a co-founder of the New Orchestra Workshop Society and frequent collaborator with the bassist Lisle Ellis. He is well versed in classical music and in all styles of jazz; he was one of the first and most convincing interpreters of Ornette Coleman's music on the piano (an instrument usually seen as antithetical to Coleman's music).

Plimley studied classical piano under Kum-Sing Lee at the University of British Columbia (1971-3). In 1978-9 he studied with Karl Berger and Cecil Taylor at the Creative Music Studio in Woodstock, NY. In 1977 he founded the New Orchestra Workshop (NOW), and he has been active in many of the ensembles associated with NOW, including the NOW Orchestra.

His work with Lisle Ellis is extensive, and includes the duo CD Both Sides of the Same Mirror (Nine Winds, 1989); When Silence Pulls, with Andrew Cyrille (Music & Arts, 1990); Noir, with Bruce Freedman and Gregg Bendian (Victo, 1992); Density of the Lovestruck Demons with Donald Robinson (Music & Arts, 1994); and Safecrackers with Scott Amendola (Victo, 1999). Most notable, perhaps, are two recordings for Hat Art: the collection of Ornette Coleman interpretations, Kaleidoscopes (1992), and (under Joe McPhee's leadership), a revisiting of Max Roach's Freedom Now Suite called Sweet Freedom, Now What? (1994). In May 2000 he recorded a live act at the 17th International Festival of New Music in Victoriaville, Quebec with John Oswald, Marilyn Crispell and Cecil Taylor. The album was released at Victo Records.

The still Vancouver based musician is a regular at the annual Vancouver International Jazz Festival."
