Background: Albert Ayler (; July 13, 1936 - November 25, 1970) was an American avant-garde jazz saxophonist, singer and composer. After early experience playing R&B and bebop, Ayler began recording music during the free jazz era of the 1960s. However, some critics argue that while Ayler's style is undeniably original and unorthodox, it does not adhere to the generally accepted critical understanding of free jazz. In fact, Ayler's style is difficult to categorize in any way, and it evoked incredibly strong and disparate reactions from critics and fans alike.
Context: Ayler routinely showcased his highly untraditional personal saxophone style in very conventional musical contexts, including children's songs, march melodies, and gospel hymns. However, Ayler's wild energy and intense improvisations transformed them into something nearly unrecognizable. Ayler took a deconstructive approach to his music, which was characteristic of the free jazz era. Phil Hardy says that Ayler "dismantled" melody and harmony in order to more deeply explore "the physical properties" of his saxophone. Ayler wished to free himself and his bandmates to improvise, relate to one another, and relate to their instruments on a more raw, "primal" level.  The intensely spiritual aspect of Ayler's music was clearly aligned with the beliefs of jazz saxophonist John Coltrane, who was profoundly affected by the "otherworldly" sounds of Ayler's music. This effect is especially evident in Coltrane's albums Meditations and Stellar Regions. Coltrane served as a mentor throughout Ayler's life, providing financial and professional support. This intensity, the extremes to which Ayler took his tenor saxophone, is the most defining aspect of his sound. His style is characterized by timbre variations, including squeaks, honks, and improvisation in very high and very low registers. He possessed a deep blistering tone--achieved by using the stiff plastic Fibrecane no. 4 reeds on his tenor saxophone--and used a broad, pathos-filled vibrato.  Ayler experimented with microtonality in his improvisations, seeking to explore the sounds that fall between the notes in a traditional scale. This technique was best showcased when he played, as he often did, without a piano, backed only by bass and drums. Ayler also resisted the standard swing beat, and instead built momentum through the frenetic speed of his improvisatory lines, which he forcefully overblew from his saxophone. Jazz historian Ted Gioia describes Ayler as a "virtuoso of the coarse and anomalous," and claims that Ayler aimed to break away from the constraints of playing notes and instead to "enter into a new realm in which the saxophone created "sound"." Ayler undeniably succeeded in doing this; he produced sounds that were unlike any made by jazz saxophonists before him. However, while some found a powerful artistic voice, even musical genius, in these sounds, others found only noise.
