As one music lover to another, I want to be certain you know about
Fantasie Variations on Tales of Love by pianist/composer Daniel Abrams.
Found it by chance after clicking on to Allclassicalmusic.com (which I did
after seeing their ad in "Opera News").  Abrams has written (they are not
transcriptions, but original music based on the themes and motifs of the
operas - and written in the style of each composer) some of the most
beautiful and heartfelt music I've ever heard on operas by Wagner
(Tristan), Purcell (Dido & Aeneas), and Weber (Der Freischutz).  He has
added some gorgeous music to the romantic repertoire for pianists.  And
when it comes to piano playing, he's simply awesome.  I would assume by
what you wrote that Abrams must be a genius!
