I don’t think you should necessarily learn drums first, but drums take a while to get good at. The issue isn’t that drums are hard, they’re pretty easy all things considered, but you have to learn what good drums are and why they are good. And that takes a long time. So I’d get started early, even if it’s not your main focus. Just a practice pad, a pair of sticks, and learning your rudiments will go a REALLY long way when you get behind a kit.
