Come on, it's Valentina Lisitsa AND Rachmaninoff. There's no such thing as going overboard with those two.
Given j_menz's above reference to "exhibit A" as evidence, I must counter your statement above by pointing out that, in a court case (not that there is one, I know), the fact that Rachmaninov is not only dead but has also been so for almost long enough for his work to enter the public domain, what I understand to be your implication that your broadly identical declarations about him and Ms Lisitsa should be treated equally is surely untenable, as any court would no doubt endorse.
Furthermore, the fact that thread title makes no reference to Rachmaninov weakens your argument above.
That's like for you, Bach and Alkan. Balkan? Yeah, that's like you discovering a composer named Balkan!
I have no doubt that there have been and are quite a few Balkan composers, although I've never encountered one with that actual surname.
Best,
