A song, an album, a soundtrack; all of these are tangible and immortal. A record is an earmark, its content an official statement of those who created it. No matter the quality, the sounds that the CD, LP or MP3 file are coded to produce will be the same on every spin. A concert, however, exists exclusively in the moment. The set list and the arrangements are never set in stone. The show is purely the product of the men and women assembled on stage working on a single take, pushing their creativity and musicianship beyond anything packaged and polished in the studio, creating a resonance that lifts an audience of thousands or greater into a transcendent state.
