The notion creates an interesting question, though ‘mdash; when DSO doesn’t have a structured set to stick with, do the members choose their favorites or rather songs that go best together? ‘ ‘ ‘ The answer came with the second set, a blockbuster jam of no less than a baker’s dozen of tunes stirred together into one long, shape-shifting groove. And it’s certainly the latter ‘mdash; joining crowd favorites with lesser-played tunes, the second set flowed smoother than a river, finding highlights in ‘Two Souls in Communion’ (sung marvelously by keyboardist Rob Barraco), two touches of ‘Not Fade Away’ and genuinely joyous ‘Touch of Grey.’ ‘ ‘ ‘ By the end of the marathon run, another ‘Not Fade Away’ pulled the crowd back down to earth just as it’d shot them up into the rafters nearly an hour earlier. ‘ ‘ ‘ While the set wasn’t Dark Star’s most exciting, it was nothing if not a solid, steady performance that nicely came full circle. The highs simply weren’t as high as the band can reach, though the lows were lush, rolling moments (see: ‘Comes a Time’ in the second third of the second set). ‘ ‘ ‘ And when it came time to walk out, the audience, though not worn out from an intense musical workout, left knowing they’d seen a full, well thought out show. A complete show.
