I'm a singer, but not much of a musician.
I can sing almost anything a baritone can be expected to sing--classical songs, oratorio arias, a number of operatic arias. I'm not much of a technical musician though. As an example, Christmas Eve I sang O Holy Night in English and French, and also did the first and last verse the next Sunday for those unable to attend our Mass on Christmas Eve. Yes, I took the optional high note at the end of the last verse.
I can listen to older of singers from the pre-stereo eras. I like tenors such as Beniamino Gigli and Richard Crooks, to name the two from that period I listen to most. (I always wished I were a tenor, like my brothers were . . ) But I like some of the older sopranos, such as Elisabeth Rethberg, Kirsten Flagstad, and Frida Leider. Rise Stevens and Blanche Thebom are probably my favorites of the older mezzo-sopranos. For basses, Ezio Pinza is by far my favorite of the older ones, followed by Alexander Kipnis. There are numerous other fine singers who flourished from around 1900 to 1955 or so, but these are the ones I listen to most.
I enjoy some of the older pianists, too. Rachmaninoff was a fine pianist, among the greatest ever. Alfred Cortot's Chopin was great. Rubinstein and Horowitz lasted well into the stereo eras, but I like some of their old mono recordings, too.
I don't like harsh sounds and this cuts out a lot of thicker music, such as older recordings of orchestral and choral music. I do have a few operatic recordings from the thirties and forties which are OK, but in those days, the voices would have been the focus, with the orchestra much more subdued than in reality. With some of those, the orchestra is pleasant enough though the frequency range is limited. From about 1955 on, there are many good recordings of orchestral and choral music.
