Sandro, can you please name your tracks accordings to the conventions ? There is a thread somewhere which explains that. Bach prelude/fues pars should be delivered in one track, with a 1-2 second silence between the parts. The name should be bach-bwvXXX-bisotti.mp3. It would also be nice it you can put in the ID3 tags as required (see that thread). Also please put in the exact details in the posting, like BWV number. Lastly, if you have 2 related pieces, please use one posting instead of two.
All this aimed to save me work... I don't like work
Now about the recordings. I do not agree with all the tempo pulling and the self-conscious dynamics in the prelude, but then I like my Bach straight and snappy, and tastes differ. The fugue is much better if still a bit old-fashionedly idiosyncratic. Very well played both of them. But that goes without saying by now.
