It was seventeen years ago today, Nevermind made its record store debut, and rock music would never be the same. Nirvana's second full-length album (and the first on Geffen rather than indie Sub Pop), Nevermind solidified the band's trademark loud-quiet song structure and marked a shift in their sound to something bigger than just grunge. While it took months for Nevermind's first track "Smells Like Teen Spirit" to become a surprise hit on the MTV, today's the anniversary of that seminal album being released unto the world. Take the time to give it another listen.
