From the point of view of the musician onstage, there can be no better sight than to look out mid-song and see a throng of people dancing.
On a good night, when the band is in synch and firing on all cylinders, the non-verbal communication between members locked into the same rhythms, anticipating one another’s next moves and simultaneously reacting to and spurring them on, is the most intimate exchange that people can have outside of sex.
When listeners are dancing in response to these sounds, this deep and visceral connection extends into the audience, the feedback loop expands, and the energy swap grows ever more intense.
You play harder, tighter, maybe a bit faster, and certainly with more spirit. You have to: The dancers depend on it.
