Anyone who has ever been to a conference will tell you they are exhausted by the end of the day. Musicians and those involved in the music industry whether it be as a teacher or provider of other services, are no different. What is different is the concerts that are put on by various groups through out the day and into the evening. You have to to qualifiy to do that here. You can't just show up with your horn and sit down and toot away!
Of course for musicians a concert by a trained group is an inspiration to fellow musicians. It gives them hope and joy that someone has achieved what they set out to do (as well as the joy of exploring different perspectives or ways of interpretation of a familiar piece of music).
This is the joy that Spirit of America wants to foster in others. Its our common goal as musicians. That is what motivates us as a group.
