Recreating a Proms concert conducted by Leonard Bernstein in 1987, the BBC Scottish Symphony Orchestra and Chief Conductor Thomas Dausgaard pair two of the best-loved and most beautiful works in the repertoire.

Mozart’s Clarinet Concerto, with its sublime slow movement, is the composer at his sunniest and most mellow, despite the fact that he was to die two months after its completion.

Mahler’s Fifth Symphony, by contrast, is the urgent work of a composer starting a new adventure, charged with new musical possibilities and a new love, expressed with impossible tenderness in its famous Adagietto.
