The cello is awesome at expressing sadness and regret
This cover of a Metallica song, “The Unforgiven”, is even better than the original. While the electric guitars of Metallica were very good at expressing the angry and resentful aspect of the person who is unforgiven, the cellos of Apocalyptica bring out the essential sadness and regret of the song. Even just as an unadorned instrumental, the music can communicate the emotions of the song.
