He is considered the Father of Grunge: The Grunge style was very popular in the 90’s. It appeared to be a messy and chaotic design, in the way the typography, backgrounds and textures were combined to form posters and magazines. This style is known as a design movement that doesn’t respect any rule of composition. Even Carson admits that his design is experimental, personal and intuitive and it has nothing to do with formal design. But if you look closely at Grunge posters, you’ll notice some rules of composition and proportion. There is a visible contrast and proportional ratio between elements, type and background.
