It costs so much to promote something these days that almost always safety is the preferred option, reference back to things which have been successful in the past. Also, people are simply not given the time to develop and find themselves and their audience as we were.

I suppose, in a way, one could say I may be less interested in my career than the audience is. Not to mean that I'm disinterested in my career, but I don't see it in terms of one stepping stone or, 'Now I'm going to go into my blue phase,' or what have you.

Being used to scientific terminology and theory it was always natural for me to push this stuff into songs.

I had then and still retain an interest in science for its own sake and as a metaphor for our current lives.
