The music of Gustav Mahler, the Late Romantic composer on the threshold of modernity, has been a firm part of the repertoire of the Symphonieorchester des Bayerischen Rundfunks ever since the early 1960s, when the orchestra's Mahler tradition was established by it's former chief conductor Rafael Kubelik. The 2007 recording that has now been reissued by BR-Klassik or Mahler's First Symphony, with the Symphonieorchester des Bayerischen Rundfunks under it's chief conductor Mariss Jansons, can be regarded as an album premiere- in that this recording has only so far been available as a bonus release forming part of the audio biography of Gustav Mahler "World and Dream." This new release is thus aimed primarily at listeners eager to experience Mahler's First Symphony under Mariss Jansons who would prefer to purchase the orchestral work separately from the audio biography.
