Ein deutsches Requiem - Brahms
Johannes Brahms (1833-1897), was a German composer of the Romantic era who used trombones sparingly but strategically.
Brahms completed Ein deutsches requiem (A German Requiem) by 1868. Brahms personalized the text rather than follow the traditional Requiem text. The writing for the trombones in this work is restrained, employed only when it really matters - solidly structural and not at all showy.
