The delicate, meditative songs Mark Kozelek records with his band Sun Kil Moon are the sort of music that can get lost in the air at an outdoor festival. Up close to the Green Stage, it felt like an intimate show, with Kozelek’s silky nylon-string guitar notes accenting his unusually personal lyrical musings about things like watching Steve McQueen movies with his dad. The rest of the band tinkered around the edges of Kozelek’s quiet plucking, creating an effect something like a chamber quartet playing jazzy folk-rock. As exquisite as that sounded, the crowd was chatty just a short distance farther away from the stage. It was the sort of festival set that seemed either beautiful or boring, depending on where you happened to be in the park. (Robert Loerzel)
