 A couple of Russian rhapsodies, and the first one was written by an 18-year-old Sergei Rachmaninoff. He and his schoolmate Yosef Levine, a great pianist, performed the premiere of that. Oh, to have a recording of that performance. This is called the Russian Rhapsody, or Rhapsody on a Russian Theme. It's for two pianos by Rachmaninoff, Joshua Pierce, and Dorothy Jonas perform.
