Modern Classical 1920s-2010s: A Spotify playlist

This week, our playlist explores and celebrates "modern classical" music; here we mean compositions that pushed the art of music forward during the past 100 years. Our list begins with Sibelius' Symphony No. 7 (1924), which is Romantic in style. However, its innovative form (a one-movement symphony) is indicative of the modern urge to challenge tradition and expectations. The pieces that follow are by no means easy listening, but they are certainly powerful. Several of them are in remembrance of historical tragedies.
