Kickstarting free, open recordings of Bach's "Well-Tempered Clavier, Book 1"

Ok, this is going to be somewhat, but not quite off topic. I’d just started watching “Demons”, a Mario Bava film. The start has a girl clutching sheet music while riding a subway. Since it was Bava, I figured the sheet music might be worth paying attention to. It was. The score was for Bartok’s ’ “Mikrokosmos” and now that I have looked it up, I would 1) love to hear it and 2) have the sheets for at least the earlier (easier) parts. One is not a problem…Two is.
