Sorry - I just have to post my preferred version I found on youtube...
Johanna Beisteiner 's version is very nice played with a lot of temperament and a nice tone. But I just don't like the way she plays the triplets - they are many times NOT triplets at all (a little bit like punctuated) - and the triplets on top of the normal eigths make the tension in the melody/accompaniment so nice, I think.
So: I like Brigitte Zaczek's version (Vienna, professor at Universität für Musik und darstellende Kunst) which plays it the way I like it much more (that's personal preference, anyway, I know...):
She plays the Mertz version but it seems to be with a few basses in ottava bassa. I tried to find out if there is a Mertz version denoting exactly that but I could find just the well known Boje collection version. Maybe someone else knows more about that.
