1985 Digital WestGerman DGG Bach works for 4, 3 & 2 Pianos Concertos played by Christoph Eschenbach (who also conducts the Hamburg PO from the keyboard) with Frantz, Oppitz & Helmut Schmidt. The owner would order all the albums that had notable recorded sound in Gramophone magazine, and would check the vinyl for flaws or issues then seal it himself (I opened this one).
