Pastel piece...just playing around

So this piece comes from a spirit I have held for a long time...I love music and it inspires a lot of my work. But this piece's story,  I was doing a show for some people that really didn't go over well for me financially or promotion wise so I pulled out my sketchbook to draw to generate some attention, people always want to see what you are drawing...Well there was a live band and I had a pretty good view of the guy on the keyboard so I did some sketches and this is what they have become...
