sifting

A little known, but still kickass, song by Nirvana. Was on their first album, Bleach, which was recorded for around $600 dollars and went on to only sell around 35,000 copies, showing little hint that Nevermind would leave them as rock legends.

Spell the smell
Wouldn't it be fun?
Search for a church
Wouldn't it be fun?
Wet your bed
Wouldn't it be fun?
Cold in coals
Wouldn't it be fun?
