Amid his piano playing and conducting, the 20 year old
Sergei Rachmaninov turned out his Two Salon Pieces for Piano and Violin as his Opus 6 in 1893.
The first sounds a bit like Mendelssohn or Kreisler but with a Russian flavor.
Romance, Op. 6/1
The second is sheer fun and a showpiece for the violin.
Hungarian Dance, Op. 6/2
