It is so passionate and stirring. The only thing is the original is not long enough for me. I wanted more variations on the theme.
If by 'the original' you mean the Rachmaninoff Variations on a Theme of Paganini, one can't fault the composition for not being long enough. Repeated playing works for me. You might like more variations but a different composer: Johannes Brahms.
