When these recordings were made (in the 1960s), schoenberg"s music was comparatively rare on record. It represented, then, the typical daring of both, the melos ensemble of london, and of the l"oiseau-lyre label for which it was originally recorded. In the extended schoenberg serenade, the melos ensemble of london was joined for one of the movements by baritone john carol case. All recordings are released on cd for the first time.
