Grunge Bold is based on the distorted font used by MTV (mainly on 120 Minutes) from approximately 1993-1995. I've spent a long time piecing together multiple sources (recordings of 120 Minutes, etc.) in order to achieve the most accurate effect. Only if I couldn't find the character I was looking for I recreated it all the while staying true to the other characters' structure.
