Brahms. The piano concertos (especially #2), the violin concerto, the double concerto, the 4 symphonies, all his chamber works, most of his songs, Ein Deutsches Requiem, Tragic Overture, Academic Festival Overture (Brahmsian humor), the many pieces he wrote for a capella choirs, especially women's choirs, his wonderful Hungarian Dances for four hands, the waltzes, especially for four hands, the two books of Liebeslieder Waltzer, his Op. 5 piano sonata, all his later piano pieces, each one a small, perfect gem, the Haydn variations, Handel variations, the cello sonatas, the violin sonatas, the clarinet sonatas, and oh the Alto Rhapsody and the Four Serious Songs. Definitely Brahms!
