To completely change gears from solo piano work, I thought we'd listen to something for full orchestra. Shostakovich's Fourth Symphony is one of my all-time favorites. It's definitely 20th century, but, like most Shostakovich, it's also quite neo-Romantic. Shostakovich's music can quickly change from showcasing sharp wit to displaying great terror. Shosty 4 sticks a little bit closer to horror.
The most famous of his symphonies is No. 5. I've always loved Shostakovich 4 and 5, but it's fascinating, actually, how different they are. Just give this a minute or so at the beginning:
Anyway, Shostakovich actually shelved No. 4 for a good long while, because he was afraid it would get him in trouble. He had somewhat of a shaky relationship with Stalin - at times Shosty was in his good graces, at other times he was under house arrest for being subversive. One such work that Stalin didn't much care for was Shostakovich's "Lady MacBeth of Mtensk." The 4th Symphony is pretty similar to said opera, so Shosty was afraid to have it premiered and get in trouble again. No. 5, then, was almost an apologetic work. It's much more palatable. Just as good as 4, but also more often heard.
I'm not an expert on Shostakovich recordings myself, so I did some light research on which was the best No. 4. I couldn't quickly and easily find the ones that were suggested, so I picked the Bernard Haitink/Chicago Symphony Orchestra recording from 2009... It was the first to come up on Spotify, and I like the picture.
Before I give too many more of my thoughts, I'd like to hear what you guys think. I'll pipe in more after that.
