Many band logos are hugely famous – everyone recognises The Rolling Stones' tongue and Nirvana's smiley face. They're on T-shirts, merch, and if you see them on a news story, you'll know which band the story is about before you even read the headline.
Band logos have evolved over time, and differ greatly from genre to genre. Generally speaking, the heavier a band's sound, and the darker their image, the more indecipherable their logo will be – and there will probably be a lot of black and white. If you've ever seen a poster for a metal festival, you'll know what I mean.
