Temporary Super Offer! 'The Miles Davis Quintet of early 1960 was an endangered, embattled entity. Davis and his frontline foil John Coltrane had been drifting apart stylistically and temperamentally for months. United in the embrace and exploration of modal devices on the trumpeter’s seminal Kind of Blue album released the previous summer, bandleader and sideman were increasingly at odds as to where to go next with the celebrated innovations.' - Derek Taylor
