Here's a Portland band who fit the phrase "flash in the pan" better than any other I can think of. Formica Man was formed by members of other bands including Karen and The Parenthetical Girls. They played dissonant, loud music and their live sets took about 15 minutes, if that. If you were lucky enough to attend one of their shows, you might have had the pleasure of hearing one of singer Aubrey Hornor's jokes in between songs (one that sticks out in my memory Q: Why did Al Capone flirt with the idea of becoming an optometrist? A: He wanted to help people, see?)
Or go to their Book of Faces page and give them a thumbs up.
