OP, since you're new to Rameau, I'll offer a recommendation. Try Rameau's Une Symphonie Imaginaire, recorded by conductor Marc Minkowski with Les Musiciens du Louvre. This is an absolutely delightful traversal of immensely entertaining music. Spirited, fun, very well-recorded.
Olaffson is a terrific pianist. I love his Philip Glass, and some of his other recordings. But in my view he lacks the playful spirit that Rameau's music calls for. I like Angela Hewitt in Rameau on piano.
