Two of the most interesting artists currently before the public, and still in their twenties, are Daniil Trifonov and Benjamin Grosvenor. Trifonov's album called 'Transcendental' on DG has Liszt playing of at least Richter's calibre, and that is of course saying a lot. Grosvenor is more like a Shura Charkassky, impish and witty, with charm and daring. Well recorded on Decca - several discs available.
Longer established, much by Murray Perahia is beautifully and intelligently played, particular more recent Sony records, though he has just switched to DG. One of his finest performances is of the Goldberg variations, which of course was Gould's calling card.
