Thanks Again, TwoLeftEars!
Based on your recco ordered the Chandos Vaughan Williams CD with "Five Variants of Dives and Lazarus." You're completely right; this is a fabulous/addictive piece and recording.
Still haven't gotten the CD but am listening through Amazon music -- that automatically adds SOME of the CDs you buy to its media player. Sadly, this audio animal only produces MP3 files and these, truly, suck for quality orchestral playback. Can't wait to get the CD later this week, There is no sense of immediacy with MP3 -- the orchestra sounds distant and muffled (am using the best settings and computer equipment, btw).
Also took your advice and picked up the Chandos Pleyel Symphonies and the CPO Sinfonia Concertantes. Amazon puts about 1/5 of the CDs you buy into the AutoRip media player and only the symphonies appeared (suspect this is licensing -- does anyone know?). In any case, the Pleyel is what I remember from the Mozart quotes -- effortless and airy with a tendency towards casualness. Still, worth investigating.
Now its back to another listen of the "Dives." It's a keeper.
