The Whigs got a sweet spot in the lineup, as they went on during sundown. In the film business, it's called the magic hour -- when there's still light out, but no sun.
The one thing I haven't mentioned was that for the most part, the band's sets didn't overlap too much. So when one ended, the other began. When they did, the conflict wasn't too great. MuteMath was on at the same time as Duke Spirit. That was a no-brainer as who to see. During The Whigs set, I ran over to shoot Ghostland Observatory, and then ran back to catch the end of The Whigs set. Luckily, when I got back, they tore into "Right Hand On My Heart." The sky behind them was all orange and there was a smooth breeze coming from the Delaware River. That my friends, was probably the high point of the day for me. All of the elements aligned to make a perfect music moment.
