Yeah, Adrian, hopefully you'll be able to more fully satisfy your curiosity about classical music. There's a whole world of great music waiting for you out there to give a listen. There's been quite a few suggestions made on the board, for example in the "stunning recordings" thread, and I'd be happy to make specific suggestions that you might be interested in.
The snippet from Prokofiev in that disc that you mention reminds me of a terrific bargain available now on his Cinderella plus Glazunov's Seasons. The British supplier MDT, which I've used with great satisfaction, is having a sale on Universal(Decca, DG,Philips)two-disc sets for about $7.80 U.S. plus about $1.10 shipping. Of course, as usual, a currency adjustment applies and Canadian shipping apparently is about a dollar more, but this set
is still a great buy.
