The AllMusic review by "Blue" Gene Tyranny states "This set is interesting primarily to hear European musicians interpret Taylor's kinesthetic directing...mostly an intense density of "free playing" (actually following specific internalized instructions and images) with almost everyone going on different gestures at once, with slow unison melodies emerging from the environment".^[4] Describing the album as “deeply moving”, The Penguin Guide to Jazz Recordings says it is “a monumental event, the colossal sonic impact tempered by Taylor’s own unflinching, instinctual control and a grasp of dynamics and dramatic possibility which is breathtaking.”^[2]
