Im guessing you need idead for filling up the flyer? 80's style ghetto blasters would look nice if you could get one positioned with the next. And try to use as many contrasting colours as you can, that was a big thing in the 80's.
The text you have looks good but add a black drop around it like graffiti usualy does, then the fill colour round that, looks kinda retro. That's about all the input i have, apart form go find some old people who remember the 80's.
