On Good Friday, 10 April 1868, Joachim and his wife joined their friend, Johannes Brahms, in the celebration of one of Brahms' greatest triumphs, the first complete performance of his "German Requiem" at the Bremen Cathedral. Amalie Joachim sang "I Know that My Redeemer Liveth" and Joseph Joachim played Robert Schumann's "Abendlied". It was a glorious occasion, after which about 100 of the composer's friends, the Joachims, Clara Schumann, Albert Dietrich and his wife, Max Bruch, and others gathered at the Bremen Rathskeller.
