When you go to a typical concert, the experience is broken up into songs. Unless the band is theatrical (i.e. Pink Floyd's The Wall tour), there is no encompassing arc.
Cloud Cult defeats this limitation, usually in duplicate or triplicate, as several artists develop their reaction to the music on canvas before you as it hits them live. By the encore, the cumulative effect of song after song has colored, tainted, painted and repainted itself. Differing experiences of the same sonic environment develop and confront you from every side. And when the lights come on after all is sung and done, the finished works stand as testaments to the ideals that rang out onstage and are carried home aglow in every departing car.
See this band if you care about music. Trust me.
