"Torsten Müller (born November 25, 1957 in Hamburg, Germany) is a free improvising bassist in Vancouver, Canada. He plays a 5 string double bass. He lived in Bremen and Hamburg from 1976 to 2001, where he started his musical career and worked as a radio host and producer at Radio Bremen, a public radio and television broadcaster.

He came into the free improvised music scene in the mid 70s, first playing with Free Music Communion (an ensemble with guitarist Herbert Janssen and pianist Udo Bergner) recording three LPs on their own Fremuco Records label. He was a member of the large improvising ensemble King Ubu Orchestra for 10 years.

Torsten Müller has performed concerts all over the world with a diverse array of improvisers, including Evan Parker, John Russell, Jon Rose, Joelle Léandre, John Zorn, Arto Lindsay, Lol Coxhill, Alexander von Schlippenbach, Paul Lovens, Phil Minton, Charles Gayle, Melvin Poore, Paul Rutherford, Peter van Bergen and Alfred Harth.

He moved to Vancouver, Canada in 2001 where he has been performing at the Vancouver International Jazz Festival and acts as co-curator of the annual Time Flies Improvised Music Festival. He plays in various ensembles, including Vancouver based drummer Dylan Van Der Schyff's Bande X and his own ensemble, Hoxha, with British trombonist Paul Rutherford and Dylan Van Der Schyff."

"One of only a handful of drummers equally well known for his work as a composer, Brooklyn-based Harris Eisenstadt (b. Toronto, 1975) is among the most individual and prolific musicians of his generation. His resume includes studies with some of the most respected names in jazz and improvised music, West African and Afro-Cuban drumming, and performance credits in jazz, film, theater, poetry, dance, contemporary concert music and opera.

Eisenstadt has performed all over the globe, received grants from organizations such as Meet The Composer, American Composers Forum, Canada Council for the Arts, and appeared on more than 60 recordings since 2000, including twenty as a leader. Recordings of his compositions often appear on the Songlines, Clean Feed, No Business, and 482 Music labels, and are consistently included on critics' best-of lists. Recent honors: Rising Star Percussion Percussion, Arranger, and Composer categories of the Downbeat international critics poll; Best Album, Drummer, Composer categories of the El Intruso international critics poll.

His first work for orchestra, Palimpsest, was premiered by the American Composers Orchestra, as part of the Jazz Composers Orchestra Institute at Miller Theater, Columbia University (2011). Eisenstadt's second orchestral work, Four Songs, commissioned by the Brooklyn Conservatory Community Orchestra, was premiered at the Brooklyn Museum (2013). His first string quartet, Whatever Will Happen, That Will Also Be, was premiered as part of Eisenstadt's twelve-set residency at The Stone in NYC (2015). As a writer and radio producer, he has contributed to National Public Radio and AfroPop Worldwide. Eisenstadt is also an active AfroCuban batá drummer in New York and a longtime researcher in African and diaspora vernacular traditions. He has travelled to West Africa twice (Gambia, Senegal) to research Mandinka and Wolof music, and to Cuba twice (Matanzas, Havana) to research Afro-Cuban music."

"Paul William Rutherford (29 February 1940 - 5 August 2007) was an English free improvising trombonist. Born in Greenwich, South East London, Rutherford initially played saxophone but switched to trombone. During the 1960s, he taught at the Guildhall School of Music and Drama.

In 1970, Rutherford, guitarist Derek Bailey and bassist Barry Guy formed the improvising group Iskra 1903, which lasted until 1973. The formation was documented on a double album from Incus, later reissued with much bonus material on the 3-CD set Chapter One (Emanem, 2000). A film soundtrack was separately released as Buzz Soundtrack. Iskra 1903 was one of the earliest free improvising groups to omit a drummer/percussionist, permitting the players to explore a range of textures and dynamics which set it apart from such other contemporary improvising ensembles as SME and AMM. The group's unusual name is the Russian word for "spark"; it was the title of the Iskra revolutionary newspaper edited by Lenin. The "1903" designation means "20th century music for trio"; occasionally Evan Parker played with the group (Iskra 1904) and Rutherford also at one point assembled a 12-piece ensemble called, inevitably, Iskra 1912. The group was later revived with Philipp Wachsmann replacing Bailey, a phase of the group's life that lasted from roughly 1977 to 1995; its earlier work is documented on Chapter Two (Emanem, 2006) and its final recordings were issued on Maya (Iskra 1903) and Emanem (Frankfurt 1991).

Rutherford also played with Globe Unity Orchestra, London Jazz Composer's Orchestra, Centipede, the Mike Westbrook Orchestra, and the Orckestra, a merger of avant-rock group Henry Cow, the Mike Westbrook Brass Band and folk singer Frankie Armstrong. He also played a very small number of gigs with Soft Machine. He is perhaps most famous for solo trombone improvisations. His album The Gentle Harm of the Bourgeoisie is a landmark recording in solo trombone and his 1983 Trio album Gheim, recorded at the Bracknell Jazz Festival is another acclaimed work.

Rutherford died of cirrhosis of the liver and a ruptured aorta on 5 August 2007, aged 67."
