This movement in A Minor for Piano, Violin, Viola and Cello was written in Mahler's sixteenth year and it is mature beyond his years. Only this movement has survived as he destroyed the remaining movements. Mahler was studying in his first year at the Wiener Conservatory. When Mahler sent this work to his publishers, they rejected it. What arseholes! That led to Mahler destroying the other movements. This survived. This movement got its first performance in Wiener with Mahler on the piano on 12th September 1876 and it was laid to sleep until it got its next performance on 12th January 1964 in New York by Peter Serkin playing the piano with the Galimir Quartet. This piece was found among the effects of his widow Alma after her death in 1964 in a folder labelled 'early compositions.'
