For me, something will come in my head and I'll either end up calling my cell phone to record it, or I'll just pick my guitar up and see what comes out. Sometimes it sucks, sometimes it doesn't. So there's really no set method behind it.
It's funny how sometimes how the public some people think I was born like this. That I maybe I sleep and I do big muscle, but its a lot of work to look like this and to be in this kind of condition.
