Hooked on Classics was really original and got a few people into listening to classical music who didn't normally take any interest in that type of music. I grew up on the Classic Experience CD's, same idea putting a load of well-known pieces of music on a CD. That really helped me develop a taste for certain types of music, though my dad hated them.
Anyway, what about.....
Some great pieces from Grieg who was one of my favourite composers from early on.
