"Sliver" is a short, two minute long song performed by Nirvana and released on their Incesticide album, an album of outtakes and rarities.
The song tells the story of a young child who is being baby sat by his grandparents while his parents go to a show. He engages in various activities, all while asking for his grandmother to take him home. At the end of the song, he wakes up in his mother's arms.
When I first heard this song, I assumed there was something else going on: Kurt Cobain screams that loud, and based on Nirvana's general topic matter, I assumed this was a song about child abuse, that there was a more nefarious reason why he didn't like being at his grandparents. It appears, however, that the song is just what it seems to be, a simple sliver of life.
It also says something about Nirvana that after a decade of heavy metal bands trying to outdo each other in aggression and morbidity, Nirvana could manage to seem fresh singing songs about things like bored children not liking dinner.
