For those who are not into rock music or music in general necessarily, this article is still worth reading and thinking about. A couple of lines stand out for me, especially: "...every group has a threshold for tension that represents its optimal level of conflict. Uncontrolled conflict can destroy the group, but without conflict, boredom and apathy set in."

This is consistent with my own experience, both in bands and in companies, and perhaps in personal relationships also. A certain amount of friction is actually optimal in terms of output of the band / company / couple.
