What LP shows what analog can do?

I'm relatively new to analog. I've bought up some $1 records, and many sound surprisingly good (though I don't have a cleaner, so some are cracklier than I'd like).

I'd like to buy a couple of new LPs (probably from MusicDirect) that are at the very top sound quality. Of course, music quality counts too. So really I'm looking for suggestions for the record you put on to impress your friends (to show them the difference from CD), or to sit back and truly enjoy just how good analog can sound. I sort of have classical in the back of my mind, but I'm open to whatever.

Thanks.
