Grunge is not dead! Neither is punk!
The proof is the Overbeat font! It has got both grunge and punk in the one and same. The letters are grungy, and punked up with a sort of halftone slime effect. It's hard, it's tough and perhaps even scary!
Play around with the font and you'll quickly notice the variety of the font. Each lowercase letter has 4 different versions and there is ligature substitution for most common uppercase double letters!
