"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.

Murray 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."

He later recorded under his own name for ESP-Disk and then when he moved to Europe for BYG Actuel."

"Arthur Doyle (June 26, 1944 � January 25, 2014) was an American jazz saxophonist, flutist, zanzithophonist and vocalist.

Arthur Doyle was born in Birmingham, Alabama, in 1944. He was inspired to play the saxophone as child, after watching Louis Armstrong and Duke Ellington play music on television. He received a degree in Music Education from Tennessee State University. His first professional performance was with trumpeter Walter Miller, a Sun Ra alumnus. He often performed with Gladys Knight & the Pips, among others, in the R&B genre as well as in jazz. Although he performed primarily in Nashville early on in his career, he did go on tours that took him as far as Detroit. Doyle was not initially interested in free jazz, but after a performing for a Black Panthers festival he gradually gravitated toward free jazz, and sometimes appeared in concert with Pharoah Sanders and Sun Ra. Arthur Doyle's first recorded appearance was on Noah Howard's album The Black Ark. He would later appear on Milford Grave's album Babi Music, and Alan Silva's Desert Music, as well as performances with The Blue Humans. His first recording session as a leader was on Alabama Feeling, released in 1978. He appeared on a number of recordings in the 1990s and throughout the first decade of the 2000s as a leader, solo artist, or sideman. His last performance was recorded in 2013 and released on DVD."
