Tchaikovsky is NOT 2nd rate. Tchaikovsky has been at the heart of the repertoire for over 100 years. Futwangler, Toscanini, Monteux, Munch, Mitropoulos, Bernstein, Karajan, Ormandy, Szell, Reiner, Stokowski, Mravinsky, Ozawa, Heifetz, Stern, Rubinstein, Horowitz, Mstislav Rostropovich, and Yo-Yo Ma, all recorded Tchaikovsky many times over and now the likes of Gustavo "The Dude" Dudamel, Lang Lang, and Yuja Wang, are still revisiting Tchaikovsky. I'm not going to argue against all that.
