Who? What? Why?
Let’s take these one at a time.
Who: I’m Tim. I’ve been making bad music for myself for years.
What: Letter Seventeen is my “band”, or at least the name I’ve wrapped around my musical projects.
Why: The short answer is “because I can”. The longer is answer is that this gives me an excuse to learn more about GarageBand and possibly other recording software. I’ve had all of these musical ideas in my head for years. It’s time to let them out. I expect it to be quite ugly quite often, but I might occasionally do something you like.
