Musicians who are artists

I am doing my a level art exam in 4 weeks time, and for my brief i am looking at producing advertising for sonisphere music festival [i'm not really, it's just something i liked the sound of]

And i am now struggling to find suitable artists for artist research.

Can anyone suggest to me a rock/metal musician who either paints [in a style related to the music] or is a tattooist?

thanks in advance

Kristian Wåhlin? He's done a crapload of album covers for various bands, and has played in a few bands.

Chaney from Inepsy does all of their artwork, and has done artwork for a few other bands as well.
