I bought this shortly after my first visit to the Concertgebouw itself, when I was bowled over by the hall's superb acoustics and atmosphere. So these live broadcast recordings were pungent evocations of the experience. But even without that, this is a box worth having, if you can afford it. The first two discs alone are dynamite: a marvellously dramatic, idiomatic account of Bartok's Bluebeard's Castle with Ivan Fischer and Hungarian soloists, followed by one of the best Mahler Fifths I've heard, from Tennstedt in 1990.
