The Sound of Silence was written by Paul Simon and first released by Simon and Garfunkel in 1964, with an electrified version becoming a United States number one hit the following year. Its opening line about darkness and its restrained folk sound made it an enduring symbol of quiet reflection. Decades later, Disturbed released a powerful cover in 2015 that introduced the song to new listeners and fuelled its use in videos, edits and memes, where a few seconds are enough to signal seriousness, sadness or dramatic irony.
