I really liked that first one.
Got more similar to that?
Hmm, well Rachmaninoff's 2nd piano concerto sounds pretty similar. Its theme develops slower but it's incredible the first few times you listen to it.
Here's Mozart's 21st piano concerto 2nd movement, it may sound very familiar.
If you didn't like those, here is an arrangement of Schubert's "Schwanengesang", song no.7. It is just unbelievably beautiful
I hope I found what you are looking for?
It's kinda of late here and I'm going to sleep, I will post some more music tomorrow :D
