"Elevator mood music" and "workplace functional music" interrupts the ebb and flow of our existence channelling us like Las Vegas travelators. Smoothing the way. A recorded piece of music plays in its own time frame -we observe. Live music meshes with the continuum we are living. Musicians sense acoustical shifts and audience temperature changes and act accordingly. Even an earthquake could leave a mood music CD player intact calming the ruins or trying to hasten imaginary commuters on fractured platforms.
