the ego and creativity

I have been thinking a lot about art and creativity. Eckhart Tolle talks a lot about the human ego and how the ego makes us behave in negative ways but I have found myself wondering what would happen to our creativity if we lost the ego. Isn't it the ego that drives us to be creative - to produce, art, theatre, music etc? Obviously some of the arts are more ego-led than others and similarly some artists make their egos the sole focus of their work (Tacey Emin is an example that springs to mind and Antony Gormley). But would we still have the drive to create if we were ego-less, existing only in the present moment?
