From Designer To Designer, Help!

[bboy1]

Ok guys so I have a client that asked me for an isotype (Simple vectorized icon) that represent the genre ALTERNATIVE ROCK. This kind specificaly:

. The genre represents being rebel, express lot of emotions and incites to move your body very easly. So after a few sketches he decided for something like this: http://postimg.org/image/jdregnmb1/. But he wants to add some more objects or things that represent the genre, TAKING IN MIND THAT IT'S A SIMPLE VECTORIZED ICON. So, what do you guys think I should add? I know it's my work but I'm looking for some outter inspiration. A simple paint sketch will be enough. I appreciate your help and it'll be rewarded ofccourse! Cheers PD: Writing this post took me like 1 hour, I'm so stoned that I just stare at the twinkling | from the text line.
