Recently a saw Jonathan Ross interview Damon Alburn (famous as Blur's front man) and Jamie Hewlett (who comic enthusiasts will know as the creator of Tank Girl).
They told a story about how, a few years ago, they were sharing a flat in London. Watching the manufactured bands on MTV, they became disillusioned— so they decided to manufacture their own band. A cartoon band: the Gorillaz. Quite amazing to think, this month they won the MTV award for Best Band despite insisting there isn't a band.
The Band Characters are very detailed, it seems they have almost deliberately given each character deep personality— each with detailed interests. If you have a spare day you might want to take a look at their website. This is a whole new world.
