In a recent exchange of e-mails I recommended listening to Sergei Rachmaninov’s Symphony No.2 and his Piano Concerto No.2. Both pieces can be found on the Romanian site Trilulilu which I’ve mentioned (and embedded music from) before.
Below are one movement from each of the aforementioned pieces of music. Go to Trilulilu to hear more!
Rachmaninov, Symphony No. 2 in E minor, Op. 27, 3rd movement: Adagio

(On YouTube you can even hear Rachmaninov himself perform this movement from his own piano concerto).
