Being a good artist and a being a commercially successfully artists are two completely different things, though are related. We do realize that many startups if hadn't attended YC(or for that matter an accelerator like it) it could have been really difficult for them to be successful.
As being a successful artist these days is more like being a successful entrepreneur, how about starting an incubator/accelerators for artists(the ones who can be commercially successful like EDM producers DJs)? Artists attend sessions, interact with fellow artists including successful ones, understand the industry and then set out to build their careers?What do you think? Ideas? Would YC wanna do this?
Mike Shinoda of Linkin Park had an interesting answer to this on his Product Hunt AMA, read it at https://www.producthunt.com/live/mike-shinoda#comment-160950
