Business books for artists/designers/musicians?

[rNOW]

I'm looking for business book recommendations specifically aimed at artists, designers, musicians, or anyone in a creative field. A lot of business books I find are largely written by people who have built large companies and even though there are lessons to be learned from that, I do not relate to it. Would appreciate any books/blogs or videos by other creatives who talk about business side of things. 

Also any books/stories about combining two or more distinct passions into a unique life story. 

Thanks much!
