"Lithium" is one of the most popular and beautiful Nirvana songs ever released (also the best, if you ask us). The B-side to that single, "Curmudgeon," is the opposite. "Curmudgeon" is a reckless, ass-kicking of a song. It sounds like the band got too fucked up and vomited up this sloppy mess. It's not the prettiest thing in the world, but it's Kurt at his most visceral.
By the time this song was released, "Lithium" was the third single off the game-changing Nevermind album. Kurt was a star, but he was a different kind of star, and he always kept in touch with his moody, brash, punk rock roots.—Confusion
