New, I was delayed by the necessity of compiling a list that would be just ideal for you. First, you absolutely must have
The Planets ; the gorgeous music for
Swan Lake ;
Hungarian Dances;
Roman Festivals;
Scheherazade ;
Symphonic Dances;
Daphnis et Chloe ;
Slavonic Dances. These are all colorful items that should appeal to just about everyone. They should give you a good start in exploring the whole world of beautiful music that's waiting out there for those who'll just give a listen.
