Gerd Schaller is a German conductor, best known for his performing and recording rare works, including the first full recordings of Bruckner's output.

The Symphony No. 9 in D minor, WAB 109, is the last symphony on which Anton Bruckner worked, leaving the last movement incomplete at the time of his death in 1896; Bruckner dedicated it "to the beloved God". The symphony was premiered under Ferdinand Löwe in Vienna in 1903.
