During his final months with Miles Davis' group, John Coltrane participated in a number of recording sessions for Prestige and New Jazz independently of Davis (though frequently with one or more members of the Davis rhythm section) in both leader and side-man roles. This album continues the already extensive series of recordings from that period which is now in release. Limited edition of 500 copies pressed on audiophile clear vinyl (ACV). 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.
