BWV 1064 Two versions

Though I greatly appreciate original instruments and period performances, particularly the ones coming every Friday from , the very latest posting of Bach’s Concerto for three pianos BWV 1064 is a disappointing affair and shows limitations especially in the first movement. There is no clarity in the different voicings of the three harpsichords, also the tempi seem to be faster than what the ears can follow.The whole experience sounds at times muddled, obscure and rushed. I also have sometimes the suspicion that period groups spend all too little time finding the appropriate tempo rather than just using a certain formula.
I will stick with the priceless 1950 three piano recording from Poland, which addresses all these issues with great success.
