In the age of file sharing and mp3 players, even multi-platinum selling heavy metal bands need "buzz" help from Quaker City Mercantile.

Quaker City Mercantile worked extensively with Virgin Recording artists A Perfect Circle to develop and produce music videos, band-themed interactive games, band merchandise, contests and original content for two Virgin-released DVDs.

Our feeling is that bands and brands are very similar. In fact, brands could learn a lot from how bands reach out and interact with their core consumers.

Oh, and name one other ad agency that's considered cool enough to be hired to build buzz for one of the biggest metal acts in the world.
