Albert Ayler was one of the essential composers and performers during the beginning period of free jazz. He began his career as a bebop tenor saxophonist in Scandinavia, and had already begun pushing the boundaries of tonal jazz and blues to their harmonic limits. He soon began collaborating with notable free jazz musicians, including Cecil Taylor in 1962. He pushed the jazz idiom to its absolute limits, and many of his compositions bear little resemblance to jazz of the past. Ayler's musical language focused on the possibilities of microtonal improvisation and extended saxophone technique, creating squawks and honks with his instrument to achieve multiphonic effects. Yet amidst Ayler's progressive techniques, he shows an attachment for simple, rounded melodies reminiscent of folk music, which he explores via his more avant-garde style.
