I don't understand exactly what your comment is on, the interpretation by Lazar?, or the sound of Piano in my room on Youtube? Or both? You are very experienced in classical music and instruments so I put much value on your comments.
On interpretation by Lazar or his playing style. I like the way he made rise and fall of pace on a predictable passage unpredictably...very different from Yuja fast and furious which I also like but she is still predictable if one follow her enough. I also like Lazar from the way his fingers presses piano keys. His strikes are more like a 6.2 V8 big bore high torque than a Ferrari high reving of Yuja and many other modern pianists. Lazar made me feel like he had big fingers moving from one note to another so solidly with weight like a turtle taking steps. Even on a rising pace passage I feel like his fingers were slowly moving. Intriguingly romantic in my view.
On how piano sound in my room from Youtube. I am always open for criticism. I really do want to learn from experts on how different instruments not just piano should sound. I even bought a Yamaha piano that can play itself through steaming to get me more and more familiar with piano harmonic. If my piano sound weird and wrong please tell me how wrong and possibly show a video that sounds right (Yuja vid?). I want to see if my target sound is close or similar to your comment of how piano should sound. I am not saying my piano sound correct at all right now and I have my target where it should be. If you notice, I am playing with room acoustic at this point in time. It is an excellent learning seeing how room acoustic amendment changes sound.
What you heard on my video is a representative of clarity and resolution of this vinyl. The vinyl of this particular Lazar sounds above and beyond new records produced these days though.
