This week is about what you can do to start building a reputation to impress a manager.
Find Your Sound
You need to figure out who you are as a producer. Obviously, you will grow and evolve over time but the producers bring a certain vision and sound to a recording just as band's have their own sound. Howard Benson, Mutt Lange, and Timbaland all bring a different style to their recordings and artists and labels seek out their work for that signature sound. So, to have an appeal as a producer you need to find your vision and your approach. The best way to do that is probably through experimentations and listening to a lot of different music and producers.
Just like a band should begin building a fanbase and selling records on their own, one of the best things you can do is to just begin producing records. Find local or upcoming artists and try to produce their record, establish a presence online to get your name and your work out there, and just try to record as much as you can. Put your best efforts in to every project you do to build your reputation and eventually work should come to you. In the mean time, you'll establish a track record and have something to show potential managers to demonstrate your talent and your sound.
