Imo, the best interpretation that exists of
Mon cœur s'ouvre à ta voix from Camille Saint-Saëns' "Samson and Delilah". The duet that starts at 4:28 is sublime 🥲 I hate tragedies, so I don't like the opera itself, but this piece is beautiful.
Also having fun reading through the previous pages. Opinions are certainly varied on what pieces are considered beautiful (in a good way!)
