We'll be starting a regular series of roundups of the best free Photoshop brushes, in various themes; this week's Photoshop brush roundup is on the Grunge theme.

Grunge is a very bold style choice, and is characterized by its gritty style, dark, washed-out colors, and irregular shapes.

Grunge textures can be so varied, from wood to metallic surfaces, fabric, paper and more as far as textures go, but also characterizing themselves by sharp cuts, or slow fades.

They are all very similar in style, but offer subtle variations which can be used in conjunction with other similar or contrasting textures to create depth and wear.
