I think Anne Queffelec is underrated. Her Satie recordings on Virgin have gotten good reviews, but she often gets passed over in favor of Roge, Ciccolini, or even DeLeeuw.
But in my view she does a great job of giving us a playful yet languorous reading of the famous pieces of Satie (Gymnopedies, Gnossiennes) while not being as slow as DeLeeuw. In contrast, I find most of the other recommended pianists to be excessively fast and even inappropriately virtuosic. But Satie himself was not a virtuoso pianist and was an inventor of background music (or furniture music as he called it).
