Which ones do you need, pianists or composers? And what does current era mean here? Because 3 of the pianists you listed are dead.And of course the lists change because you've been given an impossible task. Are you really supposed to find out what are the 10 most popular pieces?? If so just list 10 well known pieces.
Alicia de Larrocha, sadly, is no longer with us. She died a couple of years ago.
