With the Cooper Piano Trio we have been giving Beethoven's famous op.1/3 c minor trio a whirl. It is noteworthy that his master at the time, Haydn, thought that of the set of three trios, the c minor was not going to be understood by the public (whether he liked it himself some may argue about, but to me, that's a polite way of saying it was bad, considering Haydn's preferences). In either case, Beethoven met valid resistance. People may not have been ready, but it wasn't a political ploy to suppress Beethoven.
I can understand the fuss with Beethoven because of the willfulness of his music, but if you tell me Rachmaninov caused a stir (the equivalent to good chocolate cake doing so) it wouldn't make sense.
The reason cannot be musical, it has to be external (political), and indeed it was.
When Rachmaninov premiered his First Symphony it was inevitably rigged to fail. All the old Russian old-timers (notably Korsakov and Glazunov) did not take too warmly to Rachmaninov, and they held the keys for its success. A negligent conductor, intentional tampering of the score, and a hungry-for-blood press led to one of the most stunning attempts to destroy a composer's career.
Rachmaninov fell into clinical depression for years, it was a work he had poured sometimes 10 hours of work a day over, throughout a year -- more than any other of his works. The original manuscript was lost. The only reason it was able to be reconstructed is thanks to spare orchestra parts found by chance in a Russian national library and the 2 piano score to the work that still survived. Rachmaninov never lived to hear a second performance of his work, which did go on to achieve high critical acclaim.
I need not go on about what this implies about Korsakov and Glazunov.
Why this is not more thoroughly discussed is beyond me.
