Now lets wait for official release from Munich phil on their MPHIL label. Fun fact. I've chatted with Friedrich Edelmann (principal bassoon player during Celibidache's era) and he wrote in his memoirs that the tickets for this concerts were sold out so quickly and demand for more tickets was so high that they organised extra concerts on short notice. In total they played Ein Heldenleben ten times in ten days. Always to sold out hall. Also where did you find such rare recordings?
