Mario del Monaco VS Corelli~Finale Carmen

In the 1956 edition, Franco Corelli was 35 years old In 1959, Mario Del Monaco was 44 years old (if it was a Corelli44 year old song, I probably wouldn't listen to it). All very nice. Corelli, 35, I still like. I'm trying to figure out the difference between how these two sound and how they use their breath. By putting them together, I can't quickly pick up on their differences and decide which of my own singing styles to favor (their voices, I can also produce). Soprano, of course I like Irina Arkhipova, she performs, sings better I think. Belen Amparan sang, and there was no fault. Comparatively speaking, her breath is a little lighter than Irina Arkhipova, who is more expressive of the inner world.
