A set capturing a series of documents between reedman Ken Vandermark and a remarkable cross‑section of improvisers, all recorded over the span of a few days in the Polish city of Kraków, with an additional bonus disc drawn from a Munich performance. Released by Not Two in 2019, the aptly titled Unexpected Alchemy — a nod to the Kraków club at the center of the label’s world — chronicles a meeting of leading American and British improvisers engaged in open, high‑level collective creation.
