Which came first, the music or the bangs?

So I've been listening to the new record from Grimes (AKA Canadian-born keyboardist Claire Boucher).  It's fantastic, but that's not why we're here today.

We're here today to look at bangs, because Ms. Boucher has some serious ones.  In this gripping exposé, I'll provide images of the most iconic bangs in modern music.  For each songstress, I'll also include a track that best encapsulates the haircut's artistic influence, a song that will make you say, "Wow, for better or worse, this musician has some prominent bangs."  We'll call this the BANGSIEST TRACK.  It'll serve as a great aural accompaniment to your mesmerized gazing. 

As the article comes to a close, you'll be left pondering an eternal question: does great music beget great bangs, or do great bangs beget great music?
