I have already reviewed Andras Schiff recording of Johann Sebastian Bachs The Well Tempered Clavier Book one and would just like to add that book two of the WTC is the same masterpiece as book one and this recording by Schiff is just as excellent as the recording he did of WTC book one, I can't recomend this highly enough, both the music and the recordings are Blissfull Masterpieces. This is THE music to take with you to the desert island.
Also highly recomended are the books about the WTC. 1 and 2 by Siglind Bruhn and the book Johann Sebastian Bach: The Learned Musician by Christoph Wolff
Other brilliant Bach interpreters whom I can recomend are the pianists Glenn Gould,Tatiana Nikolayeva and Dinu Lipatti. The brilliant violinist Hilary Hahn and the great German group
Cologne Musica Antiqua.
