The world is simply filled with musicians of the first order who play behind people whose names we may have come to know. It may seem difficult to believe, but many, or perhaps even most of these excellent artists prefer to remain in the background. They delight in doing what they can to make the total sound as good as it can be. Some have an innate generosity that they express by making the "star" look good. They don't necessarily need to be famous. They only want to be very good at what they do and to sound good doing it.
