Among recordings by Steve Lacy, this is the trio with Jean-Jacques Avenel on bass and John Betsch on drums, recorded at The Old Church, both sets performed that night (11/30/97) on a double-CD. (I didn't get to hear the trio live until a year and a half later, also in a church, in Berkeley).
I was curious what would be present in the pared-down trio. For one thing, Lacy being the only horn, there was more immediate evidence of the interplay betwen Lacy and the rhythm section, starting with Monk's "Shuffle Boil" and burning through Lacy originals like "The Bath," "The Rent," "Prayer," and "Blinks," all performed with a spirit of playfulness.
This version of "The Door" (like the aforementioned "Prayer") far outstrips the RCA recording.
(Thanks to Paul Secor for choosing me to do this).
