I do not think the idea of only one interpreter for a composer but this set is excellent from all points of view and we can then add other versions of this or that symphony. For starters, Mahler has never been played well and the sound is superlative. Solti, with his mastery of color and balance of the orchestra, Mahler brings out all the facets, all the passion and poésie.On tellemnt is taken by the music that even the longest movements appear short.
