As long as I can recall I've had some sort of melody playing in my head, and needed to play some instrument to get that tune out. At first I was satisfied playing the drums, just getting the beat out and playing something loud, but after a few years I needed something more melodic and so I picked up a guitar. Now I play the piano and bass as well.
I'm the sort of musician who is happiest with a room full of instruments and a lot of free time. When I sit down to record a song, I usually have at least one part already in mind, and maybe an idea of what the next part is going to be, and then it all sort of comes together one piece at a time. Sometimes my songs are a little like that old Johnny Cash song, and there might be two head lights on one side, and one on the other, but all of 'em will turn on when you flip the switch.
I wish I could think of music as some sort of competition, something that could be won, or some sort of cookie cutter process, but I don't think it works that way, I think it's an art, and it comes from sometimes troubling places in the soul, as well as expressions of joy. All I can do is try to be honest with my music, which is what I've liked about other musicians in the past. At the same time, I think that playing a live show is like playing a clown, since all that work done in private and the comfort of my home and hideway, goes right out the window.
I've found myself in some odd places in the past ten years: playing at biker bars where little old ladies flashed the band in appreciation; playing punk clubs where my drummer would exchange shots for the band for removing articles of clothing; shouting "argle bargle" at a room full of people and having them shout it right back. I've announced myself as the tallest Oompa Loompa in the world and sometimes I go by my title of Reverend, since I'm ordained in the Universal Church of Life. Playing a live show is certainly a different process than playing with myself... but now that I reread that last sentence, it's not much different.
Well, have you read enough? Did you even listen to the song while reading my little diatribe? Maybe you should listen to it again.
