Ozzy Osbourne T-Shirt Black Sabbath

Black Sabbath basically invented heavy metal by asking one simple question: “What if rock music… but scarier?” With Ozzy Osbourne wailing like a haunted banshee and Tony Iommi cranking out riffs that sound like a thunderstorm chasing you down a dark alley, the band turned doom, gloom, and loud guitars into an art form. Meanwhile, Geezer Butler was writing lyrics about war, demons, and the end of the world—basically the opposite of a happy beach playlist. The result? Millions of fans headbanging happily to music that sounds like the soundtrack to the apocalypse.
