10 Most Disturbing Hard Rock Songs Ever Released

10. Revolution 9 - The Beatles

Most people don't really come to the Beatles for something unsettling. Though the band has practically covered every single facet of the rock landscape, there aren't too many tunes by the Fabs that actually put you on edge after hearing them. Then again, if there were one tune that inspires uneasiness in the band's catalog, it has to be "Revolution 9."

Even so, it's hard even calling something like this an actual song. While it does appear as a track on the band's self-titled White Album, this is an avant garde art piece created by John Lennon to reflect his idea of resistance. Though they had already put a single out with the same title, this track feels much more disturbed than just a call to rise up.

Instead of having the bluesy groove of the former, this track is pretty much a sound collage from start to finish, with bits and pieces of instruments thrown in. It might get laughed at for its endless barrage of a man saying "Number 9," but if you listen to the rest of the song, it teeters between a work of art and pure anarchy depending on which part of the song you're in. John Lennon was always known to be the eccentric Beatle, but this art piece was enough to leave some die hard fans running scared.
