Lesure catalog, featuring some of the best recordings on Spotify: Uchida's Etudes, Michelangeli's Images, Zimmerman's Préludes, and Boulez's Pelléas et Mélisande (it's not available on Spotify USA, so I added another Naxos recording). The playlist starts a bit slow, the first indisputable masterpiece, the String Quartet, appears in the middle of the whole program, after dozens of songs and other miniatures (quite a few gems in those early works, like the charming Beau soir, encore favourite Fantoches, and the Prix de Rome pieces). After that, it's basically a cluster of monumental works.
