^ I've sure heard Locatelli before but I will check out more of his stuff if he's your favorite. I myself listen to great amounts of Bach lately. He's already surpassed everybody else in my last.fm charts. It takes a while to get to know all the piano stuff alone and to find your own favorite interprets. Everybody talks about Gould obviously, and I really like him, especially his english suites, but on harpsichord I like Keith Jarrett for instance, who has a shitload of his own jazzy stuff that I can't get into for some reason, but his harpsichord recordings are great. And then there's András Schiff, I love all his stuff.
EDIT: Oh and Gould's Goldberg Variations ofc.
