This record marks a turning point in jazz history. It may be the earliest recorded example of what Ornette Coleman later called free jazz, and it represents the first rumblings of the revolutionary movement which eventually shifted jazz thinking away from bebop. This double LP includes the complete show recorded live at The Hillcrest Club of Los Angeles in 1958 and is pressed on audiophile clear vinyl (ACV) in a limited edition of 500 copies. Audiophile clear vinyl is made using the highest quality co-polymer available and processed without any carbon additive in order to dramatically reduce the "electrical distortion" often found on records. By itself the co-polymer of vinyl is transparent. In order to make the record black in color the plant must use a carbon additive with trace metals that can become magnetized. This is what causes electrical distortion during playback. That is the reason why Doxy chose to offer these records on audiophile clear vinyl.
