Aida- The trumpet solo from the Grand March. You can probably guess what game exposed me to it.
Tocatta and Fugue, by the amazing Philidephia Orchestra. You really do need the record to hear its true glory though.
The Beautiful Blue Danube, byt the Philly Orchestra, but in 1919! Due to the styles and technological limitations of recording at the time, it is a very fresh version of it.
