41. How about some turn-of-the-century piano music by composers you've probably never heard of

that can be found on this channel:

I especially like listening to this nine-hour recording with scrolling music score:

as I work. I find most of the music fascinating and exciting and novel and inspirational. At times, I'll say, "HOW is the music written to achieve that effect I've never heard before?" and I'll look at the score to see. But that's just me. A description of that recording:

Medtner - 14 Piano Sonatas (Many performers)
"I repeat what I said to you back in Russia: you are, in my opinion, the greatest composer of our time." – Sergei Rachmaninov (1921)

It would be hard to overestimate the importance of this set. The 14 Medtner's piano Sonatas are the peak of the great Russian romanticism. Musically, technically and intellectually his works are very difficult, and don't show-off, which may explain their neglect.
Born on December 24, 1879 according to the Julian calendar (in use in Russia at that time), Nikolai Medtner was a few years younger than Rachmaninoff and Scriabin, who had long overshadowed him before his music was the object a new craze, thanks in particular to the interpretations of pianists like Emil Gilels and more recently Geoffrey Tozer, Marc André Hamelin, Hamish Milne and Severin von Eckardstein, who allow a new rediscovery of Medtner's music these years.
Recitalist and concertist, Medtner was also a professor at the Moscow Conservatory but chose to leave Soviet Russia in 1921. He lived in the United States then in Paris and finally settled in London, where he died. He had the extravagant good fortune to arouse the enthusiasm of the Maharajah of Mysore (in the state of Karnataka, India), who allowed him to record his own compositions.
Most of Medtner's works (fourteen sonatas, three concertos, chamber music works, melodies) are intended for the piano or use the piano. To put it quickly, they show romanticism, nostalgia, passion, tragic, violence (not brutal though). Medtner never recognized himself in the research carried out by his contemporaries, as he explained in his book The Muse and Fashion (1935) where he defends "the sacred laws of Eternal Art".
