I quite enjoy Brahms. His piano works are very on par with Beethoven in style and technicality. Dvorak is one that I've really been giving a lot of attention lately.

Silent Woods - a piece that deserves much more appreciation. Very beautiful. Dvorak is a lot like Beethoven in how he paints scenery with music.

His New World Symphony is in my top 10 favorite symphonies of all time.

Herbert Von Karajan's pre 80s recording is probably my favorite version. He was growing pretty feeble by the time he recorded the more well known version. This video has the thunder.
