As a music producer, I had failed to get meetings with any big labels or managers until I stopped thinking like a musician and started to empathize with record label A&R. I set up a publishing company and compiled my best songs, along with songs from other writers that I respected. Importantly, I never mentioned that I was a musician looking for a deal. I was there to help them find songs. That's all!
Almost immediately I started to get meetings that seemed impossible six moths earlier.
Better still, I was able to open doors that I hadn't even considered before. I used the same vocalist on all of my demos but I never mentioned that he wanted a deal. After several meetings showcasing my songs,a major management company asked who the vocalist was because they felt he would suit their label.
Becoming a publishing company or production company was the best move I made as a musician. I learned that in order to get in the back door of the music industry you need to do something which genuinely helps the company(s) that you are trying to connect with.
You don't have to set up a publishing company, if you're a good interviewer then offer that service. Or, you could offer marketing and reviews. Try and offer great value without expecting anything in return; you may find, like me, that doors start to open.
