According to USA today, the average length of an attention span of a man in America is 23 minutes.

I couldn't concentrate on music. So I made the choice to give up my career as a musician in the frontline to deal with the business.

And if you are playing in several meters at once, there has to be a - not a rigid - but there definitely has to be a reference to a common pulse in the band.

The plot details of B movies are irrational: accept that people do things that are contradictory, against their own best interests, have short term aims & limited attention span, and do incredibly stupid things while things blow up. Apart from things blowing up, this is just like the music industry.

There is a difference between being a timekeeper and keeping the pulse or being in step with the pulse in the band.

My life as a professional musician is a joyless exercise in futility.

But above that, most mature adults can hold their attention on something for 45 minutes, whether they like it or not. But above that requires training.
