I'd have these weird experiences where I'd just be walking down the street with this chord progression in my head, this happened more than a few times, and I'd walk home and find a fax in my machine and it would match the music in my head.
I'm fortunate I have this coterie of musicians around me to help take music to next level. Being surrounded by so much creative energy, so many creative people really feeds that creativity in me.
We'll see some simplistic players for a while, who'll then get into more complicated things and evolve with their instruments. This is a cycle that happens over and over again in music.
Be honest with yourself and the way you act when you hear music. That way, when people watch, they'll see something from your heart and soul, and as a result will communicate your feeling and thought much better.
