Don Cherry, who pioneered free jazz as Ornette Coleman's right-hand man and has been noted for his collaborations with Coltrane, has moved to Sweden with his partner Moki and daughter Nene. Don Cherry, who was a pioneer of free jazz as Ornette Coleman's right-hand man and also attracted attention for his collaborations with Coltrane, gathered local musicians when he moved to Sweden with his partner Moki and daughter Nene, and held weekly meetings at the ABF (Workers' Educational Association). From February to April 1968, Don Cherry, who has been attracting a lot of attention, held weekly workshops at the ABF (Workers' Educational Association). From February to April 1968, Cherry was giving lessons in this workshop as an extension of improvisation. Göran Freese, the saxophonist and recording engineer who later recorded Organic Music Society and Eternal Now, invited Cherry and the Turkish drummer to his summer house for a series of rehearsals and jam sessions to practice the aforementioned workshop. However, this lost tape, which has long been treated as a mysterious footnote in Don Cherry's session records, has been discovered in the vaults of the Swedish Jazz Archive and is now being published. With additional bonus material from other records recorded on the same day, this is a must-have for fans!
