It's weird, I'm not sure whether I actually like Gorillaz because of Hewlett, that song was really irritating me by the end.
I saw the Hewlett Exhibition at the design museum ages ago - it was pretty cool, but just left me wanting an art of Jamie Hewlett book and the Cream of Tank Girl is not enough and too much at the same time, if you know what I mean!
I agree with radiator, the 2D stuff works much better, conceptually and graphically.
Unless the CD has some knock-out art, I'm going to find it hard to shell out for this...
