I used to enjoy working with Engineers, because they were usually well disciplined. As a matter of fact, the jobs/fields they choose are often called their "Discipline". Musicians on the other hand, well I think we all know the recurring theme of flakiness from the Band Management sub-forum. I think it's a general thing with folks who use that side of the brain more, artists, etc. Addendum: Please don't put words in my mouth. I did not say ALL or even the majority of musicians.
