Don't get ahead of yourself. In order to play 'virtuoso" pieces, you need a solid grounding, both technically and musically.
Definitely Bach. You can never have enough Bach.
A man after my own heart!
I'm sorry to tell you this, but my heart only belongs to women... and Bach.
... my heart only belongs to women... and Bach.
Haha, it wasn't a line. Just means I agree wholeheartedly.
does that make you 'Bach-urious'?
Bach is great, but it doesn't sound like what th3kangst3r means by "virtuosic". I'm assuming stuff with lots of big chords and runs and intense, hard sounding stuff. Bach is virtuosic and difficult in an entirely different way. Someone mentioned other Chopin etudes... Op. 10 no. 12, overplayed (as are most of the Chopin etudes, IMO), but still very virtuosic, also not too far out of your difficulty level. Also, look at some of his polonaises. If you're looking for a different composer (and a different style altogether), then you may want to look at some modern stuff. Some of Prokofiev's visions fugitives are short and virtuosic.
...There’s a widely known saying attributed to certain luminaries such as Benjamin Franklin, Sir Walter Raleigh, Samuel Butler, and Hudribras: “A man convinced against his will; is of the same opinion still.” i don't think we'll get much traction with a paradigm shift on the op anytime soon, i.e. he wants something that sounds flashy and impresses...i'll resist the urge to dive deeper into the implications of such a mentality of a pianistic lifetime....to the op try the Rachmnaninoff Prelude in C# minor, it's not 'fast and notey' like the Beethoven and Chopin you mentioned but it's 'big sounding' and to untrained ears sounds much harder to execute than it actually is, also prerequisite technique is much less (i.e. the price of admission here) than with some of the faster works. also even though it is inline with 'romanticism' or 'neo romanticism' it's at least contrasting somewhat to what you say you've played. (though i couldn't very well post this response without admonishing you to please step back and take stock of your long term goals. consider spending time in baroque and classical common practice period works....)
