I don't think we have to worry. A lot of people wish the music was still like it was in the '50s. There's no way that can be. A renewal may not take the form we expect. As artists, we have to be sure to keep an open mind.
People are afraid of being left behind.
They feel threatened. An 'open' mind can be an empty mind. But I still play bass-guitar. I play it on a tour with Jack DeJohnette, Herbie Hancock and Pat Metheny. A composition can be structured for an electric instrument.
