Grunge Photoshop Ideas

From my research I have seen that many similar genres to mine use abstract simple images with a lot of symbolism, especially when looking at ones like sound garden. I have also established that many of these bands look older and have a vintage look to them, it also seems that there isn't much picture of the band itself and this is possibly the style of grunge. There were some shots with the band as a whole and I have noticed that they look very serious and are not smiling. They have also clearly been darkened and do not seem to be in good light. As many of these are like this it seems to be there is a particular style and tradition of this genre. It seems that most of the art I have seen has made to look older and washed out. I researched into this and found a blog describing how this is done and the effect it has. For example, they have a detailed tutorial in order to make something look more gritty, this is a style i have seen with many grunge art and something I could use with my own. This effect is mainly done by changing the contrast of certain parts of his face and using different layers and the "curve" tool.
