Singing For Soup Poster

So my friend asked me to design a poster for a gig he was organising for a soup kitchen, he had the idea of a Campbell soup can and basically told me to run with that. This is what I came up with, wanted to do it in my own style instead of trying to directly rip Warhol. The whole colour scheme looks like Malboro cigarettes, especially the cigarette filter looking background, hopefully smokers will be attracted to it... The bands I've included there were purely to show different font sizes and such and I have no idea why those were the only band names that came into my head...
