Nivana is one of the best bands ever. One hit wonder?
Every song on Nevermind is awesome, particularly Lithium, In Bloom, On a Plain, and of course, Smells Like Teen Spirit. Other songs to check out are Heart Shaped Box, Dumb, Very Ape, Pennyroral Tea, and All Apologies, all from In Utero, and then there's Dive, Sliver, and Been a Son from Incesticide. Great songs, great band.
