Who are the most prominent pianists today?

Question

I know of Martha Argerich, Lang Lang and Evgeny Kissin. Care to expand this list for me?

Answer 1

Here are some I can think of:
Krystian Zimerman
Mikhail Pletnev
Daniel Barenboim
Benjamin Grosvenor
Vladimir Ashkenazy
Marc-andré Hamelin
Leif Andsnes
Helene Grimaud
Boris Berezovsky
Freddy Kempf
Mitsuko Uchida

Answer 2

Adding to the list:

Howard Shelley
Maurizio Pollini (he might retire soon because of health)
Murray Perahia
Nikolai Lugansky
Ronald Brautigam
Stephen Hough
Yuja Wang

Of those above, in my opinion Stephen Hough is at the front of the class.

A comment on a prior response, both Ashkenazy and Barenboim are basically conductors now rather than pianists.
