To start of i thought id start researching music illustration, this is a very broad search so im not going into anything too deep early on.

 

These 5 images were the best out of the search i did and i found that the music illustration search is way to broad and so im going to look into different styles of music and the illustration of that.
The 1st image and the 3rd image catch my eye the most i love the rough style of it and it feels much more arty and creative that the 2nd images style.
