The pianists discography great site around pianists, composers, recordings, taking full advantage of the medium, opening every perspective under which you would like to search or filter the vast material. Imagine every word of a linear discography turned into a link.
some of the discographical treasures I could find. Thanks to all compilers! I excluded CD-only discographies, everything too private (my-collection-sites) and most of those focussing mainly on CDs (giving the dates of an earlier LP only when not reissued on CD).
Beethoven op111 an annotated list of recordings / from here you will find many more interesting sites with lists of recordings (rather than discographies) of single works
Da Ponte/ Mozart: Così fan tutte a web- essay annotating each number of my favorite opera, offering a shift of perspective (towards theatre) with unforseen results. (in German). - Listed here for no other reason than me having written it taking a break from records.
