Kurt Cobain: a magical ear and a monster guitar sound.
KURT COBAIN: GETTY
Four chords. That’s all it took to shatter the world order of electric guitar. Leading out Nirvana’s watershed second album Nevermind in September 1991, the brittle intro to Smells Like Teen Spirit was almost laughably prosaic. The presiding lords of the hair-metal scene wouldn’t even have deigned to play it as a sound-check warm-up. None of them could have realised they were hearing the gunshot to kill their careers stone-dead.
