67/1: I like the happy mood interpretation, especially the scherzando part. The pp don't sound much different to the p parts, if at all. So the differences between the dynamics parts could be more. Also, the 16th notes on some RH figures could come even more "sharper" from rhythm to enhance the lively manner. Beside that, it sounds very good to me - surely no easy task to play those RH double note parts like in bar 5/6 and similar, but you managed it well.
67/2: With that I don't get so much warm with the interpretation. It could really sound more cantabile, lyrical. Again, the pp parts, and especially the sotte voce part - it is not "half the voice". Maybe the left pedal would help. And did you leave out some 3rd beat LH notes in the first some bars?
67/3: I like it, also the melody phrasing.
67/4: Here you play with a bit rubato, and it works well, could be even a bit more, also a bit stronger riten. on those places. You phrase the melody very nice and let it end soft. In the middle part there is a fermata - I could imagine that fermata effect is stronger if you would have silence there instead let the notes ring (that means like it is written). Beside that, really tasteful played!
68/1: The single one Mazurka I could imagine to really use as rough countrymen dance music. The groove for that is captured very well!
68/2: I really like that very much! You play the 16th figures with precise rhythm, and your trills are fast, pretty evenly, and above that, soft. Can't do that - my trills are not that soft! Very good dynamics in the poco piu mosso section. Shows that you CAN play pp!
68/3: Good phrasing, I like those staccato phrases you invented (they are not in the sheetmusicarchive score, but sound well to me!). Also, you play really soft at the end and on other places, and that tone color sound great that way to me.
68/4: It would sound better to me softer played, as soft as anyhow managable at the beginning and end, and with more rubato, more breathing beetween the phrases. Last composition from Chopin, so it is stated in the sheetmusicarchive score. So is the mood - dreamery, sad, as if the life fades out softly. An interpretation approach is of course always just personal opinion, everyone can see it in another perspective.
The Granado pieces - Oriental: Great! I like that melody driven rubato and the dreamery playing. Shows that you can play in that style if you like - I wished you would implement that stronger too in this or that Mazurka, but again ... personal taste. The Fandango sounds good to me too.
All in all those are respectable quality recordings, confident played. Your output is really unbelievable, independent from that you claim to play those Mazurkas already since decades. My outmost respect for that!
Large output as usual from your recording sessions. Never understood how you do it and I am similar to Mindenblues here...slow learner.
Hehe, I insist upon learning even slower than you Robert (not to mention Chris of course, he is in another learning league) - I never could learn all Chopin preludes within some months like you did.
