Introduction: A Hidden Gem of the 20th Century Mieczysław Weinberg (1919–1996), a Polish-born Soviet composer and close friend of Dmitri Shostakovich, wrote over 150 works, yet remained relatively unknown until the early 21st century. His Trumpet Concerto in B-flat major, Op. 94 (1967) is one of the most significant – and demanding – additions to the trumpet repertoire. Often compared to the concertos by Haydn and Hummel in its classical three-movement structure, Weinberg’s concerto infuses that form with dark Slavic lyricism, biting irony, and virtuosic fury.
