There are a lot of parallels between doing a sequel and doing low budget movies, which is they give creative parameters. As a creative person myself, I work better with parameters as opposed to anything goes.
As a creative person, you want to have a foothold and sense of progress.
Before I was working professionally, I would do YouTube covers. But as a creative person, it was really hard for me when I wasn't releasing my own music. That felt unnatural to me.
I think if you speak to any creative person, there's something so powerful - so intoxicating, if you will - about discovering another voice, another instrument, another way of looking at things, another way of perceiving things.
