Christopher Cottingham, of Ann Arbor, Mich., lead vocals for the Chris Canas band, stops playing his guitar to push out a high vocal note Thursday at the sunset concert. Derek Wyatt and Josh Thompson, of Herrin, watched from the foot of the stage that night. “It’s our two year anniversary so we’re out here having a good time,” Wyatt said. “We go to every single sunset. Every time.” Thompson said the concerts are a good social outing. “We see friends we haven’t seen in forever,” he said. “we see friends we see every day, It’s a gathering.”
