John Coltrane: Interstellar Space [Impulse, 1974]
These duets between Coltrane on tenor (and bells) and Rashied Ali on drums sound like an annoyance until you concentrate on them, at which point the interactions take on pace and shape, with metaphorical overtones that have little to do with the musical ideas being explored. European, Oriental, African--I don't know. But amazing.
