Last December Mike Reed’s People, Places and Things played a terrific show at the Hungry Brain, devoting one of their sets to treatments of modern classics by their contemporaries in the Amsterdam free jazz scene, including Joost Buis, Guus Janssen, and the late Sean Bergin. Reed’s group is currently on tour in Europe and yesterday it was in the studio to play some of that material, where they were to be joined by some of the players who wrote the material. One of the tunes slated to be tackled was “What Happened at Conway Hall, 1938?” which appears on a new album by the fantastic Dutch cornetist Eric Boeren.
