너바나 : Nirvana
This is a tribute album by Korean underground rock bands. Participated bands are WeepeR (In Bloom), CryingNut (Everything and Nothing), BadBoysCircle (Polly), BadTaste (Smells like Teen Spirit), RainySun (Dumb), NoBrain (Lithium), Cocore (Spank Thru), EonNiNeIBalGwan (Come as You Are), HeoBeokJi Band (School), and GalMaeGi (Gallons of Rubbing Alcohol Flow through the Strip).
All the tracks were quite well done. I am not much of a Nirvana fan, so I really can't compare how different each rendition is to the original, but by just listening to them, they all sound very good. Among the bands above, only EonNiNeIBalGwan has their own album released AFAIK.
