There’s a Wilco song called “Less Than You Think” that is 15 minutes long. But it’s really a 2 minute song followed by 15 minutes straight of distorted white noise. Not a true “hidden track” but similar. Released in 2004.

Sometimes, Wilco can make “distorted white noise” sound good. But here, they don’t even try. It’s not pleasant at all and it’s not supposed to be.
