If your business is music, then relationships are everything. A hero of mine once said 'Do you think the members of the New York Philharmonic know each other, never-mind like each other?' 
 
That person had a point but the dynamic is certainly different in a trio traveling by bus from city to city having to bear witness to the eccentricities of one another. I was in bands for a handful of years before I just didn't have the energy to compete any longer with all of the egos and, what I remember as, ill-informed opinions. It didn't matter what the situation was. We could have been driving to a show and the trailer wasn't positioned just so or nearing fisticuffs over how much mids to attenuate from the top snare mic during a session. Sting said it best when he said 'There is no room for democracy in rock music'. 
 
The first and foremost ingredient to success in this business is great songs but the point that I'm making is this, if you're in a band with a bunch of blokes that you like personally but may not be amazing players, you might get far because your chemistry is a contagion upon your audience. On the other hand, if you're surrounded by great players that aren't the nicest, ethically and morally upright people you've ever met, you may also go far because the music is great and your audience knows it. They may even become aware of the controversy surrounding the everyday goings-on in your act and see that as all the reason in the world to attend your shows. What's a little bloodshed among musical compatriots? All is fair in Rock & Roll.
