The music industry. In my youth I tried this with a 'worldly' band and it bombed. We were bleedin' good too. All own songs with the odd cover. We had a track distributed around Japan but no takers.
It reminded me of turtles that are born. Hundreds of the lil'buggers crawling to the sea. All good turtles but some die or get eaten by birds. Only a few turtles make it. It was a turtle disaster for us.
I was associated with a local band that got a contract. They were a brill band but didn't read the contract. It was a 'hands off' contract. The record company was promoting a rival band and didn't want this band I know overshadowing the promoted band. They were left to fizzle out.
Don't lose heart despite my comments above. Perseverance! Dare I say: 'He that endures to the end.....'? Nah, I won't say that.
Good luck with your art.
