A lost Beethoven oboe concerto got a performance this weekend. “Two Dutch Beethoven enthusiasts have pieced together the musical clues, put them into 18th-century orchestral context and reconstructed the second movement of the only oboe concerto Beethoven ever wrote. The slow, melodic Largo movement of the Oboe Concerto in F Major was performed Saturday night in Rotterdam and billed as a ‘world premiere’ – even though the full concerto was performed at least once before, 210 years ago.”
