Haven't you noticed how many ultra-famous composers have works that are nowadays nearly never performed live and can be hardly obtained recorded?
Tchaikovsky: Piano Concertos Nos. 2 and 3; seems that people lack interest for those works after hearing the super famous No.1
Liszt: All of his choral and religious works
Dvorak: All of his symphonies before the 7th
Saint-Saens: Christmas Oratorio, Op.12
Grieg: Symphony in C minor
Wagner: Symphony in C major
...just to start the list.
Why does this happen, if many of these pieces also contain catchy melodies and are written with their composers usual mastery?
