Gustav Mahler (1860 – 1911) was a late-Romantic Austrian composer. As a composer, Mahler acted as a bridge between the 19th-century Austro-German tradition and the modernism of the early 20th century. While in his lifetime his status as a conductor was established beyond question, his own music gained wide popularity only after periods of relative neglect. Mahler became one of the most frequently performed and recorded of all composers.
Hector Berlioz (11 December 1803 – 8 March 1869) was a French Romantic composer, best known for his compositions Symphonie fantastique and Grande messe des morts (Requiem). He also composed around 50 songs. His influence was critical for the further development of Romanticism, especially in composers like Richard Wagner, Nikolai Rimsky-Korsakov, Franz Liszt, Richard Strauss, Gustav Mahler et al.
