I listen to a lot of classical music, mostly solo, a lot of piano, with a strong preference for the more ethereal and less bombastic.
A good intro is "Great Pianists of the 20th Century", featuring most of the best.
The best pianist of my lifetime was Sviatislav Richter, and he made hundreds of recordings. Among my favorites are the Chopin Nocturnes and the Rachmaninoff Preludes.
The greatest living pianists today are Alfred Brendel, Daniel Barenboim, and Vladimir Ashkenazy, though I suspect none are playing recitals today, but still conducting. I suspect many of you audiophiles might appreciate Barenboim's "On My New Piano", on which he plays a piano with a little different design, inspired by his visit to and playing of one of Chopin's pianos.
Other favorites, dead or alive, old and not so young:
Emil Gilels
Vladmir Sofronitsky
Claudio Arrau
Michail Pletnev
Evgeny Kissin
Grigory Sokolov
Andras Schiff
Angela Hewitt
Aldo Cicollini
Martha Argerich
All my recording are high definition (mostly flac), downloaded free torrents off the internet.
I find recordings using several sites, and I use QBitorrent to manage the downloads to my external hard drive. My first hard drive (4TB) is full, and the second one (5TB)
is now functioning.
