I bought this CD mainly because of the Moonlight Sonata and have to say that I am completely satisfied. The first part "Adagio sostenuto" is very quiet (is also the composer so provided), would for me but might be recorded bit louder. Otherwise, the quality of the recordings is very good. The other pieces I like to listen to (although I otherwise tend to Rammstein reach etc.). All in all I highly recommend this CD to anyone who can do something with Beethoven or classical recommend (and the price is right, too). Have fun with it.
