There's nothing quite like the sound of a guitar creating feedback.
No matter what you're doing or where you are, if you hear that sound you immediately feel 10 times cooler. And if you're a fan of really any kind of rock or rock-adjacent music, it's a sound you're well acquainted with.
But what if that feedback held a secret message? That's precisely the case if you listen closely to the end of 1979's "London Calling" from the all-time great band, The Clash. Can you decipher what's being said?
