Orchestra season opens at the Mann - Pittsburgh and the Dead

Warren Haynes and the Pittsburgh Symphony Orchestra Tuesday night at the Mann.

With the c. 1960s Joshua Light Show turning and bubbling away above the Pittsburgh Symphony Orchestra, the Mann Center Tuesday night opened its very-pop-oriented orchestral season. Guitarist Warren Haynes was guest for a "Jerry Garcia Symphonic Celebration," stirring an audience of about 4,400 to dance in the aisles. This slideshow captures some moments back stage and out in the house.
