Symphony No. 4 - Brahms
Johannes Brahms (1833-1897), was a German composer of the Romantic era who used trombones sparingly but strategically.
In Brahms’s Symphony No. 4 in E minor, Op. 98 (1885), the three trombones appear exclusively in the fourth movement, where Brahms reserves them for the opening ominous chorale theme (adapted from Bach - derived from a bass line in Cantata BWV 150).
