Phil Freeman / Burning Ambulance: "When writing my book In The Brewing Luminous: The Life & Music Of Cecil Taylor [...] I was astonished to discover just how much of Taylor’s music was written out, then transmitted to the other members of the ensemble through lengthy and rigorous rehearsal. One of his groups might put in months of eight-hour days in order to learn a piece that was only to be performed a single time. As bassist Alan Silva said of Taylor’s 1966 Blue Note album Unit Structures, 'Yes, there’s a score. Nobody plays ‘Unit Structure’ in a jam session! That album took us four months of rehearsal.'"
