Best Guitar Jam: The Arcs with Joe Walsh and Glenn Schwartz
Three hours after Gary Clark Jr. set the polo fields aflame, the Arcs delivered their own kind of blues explosion, closing their early evening set with a three-guitar jam representing multiple generations. The blistering, garage-y blues-rock side-project for Black Keys singer-guitarist Dan Auerbach released a debut album last fall. But Auerbach is already expanding on the concept by collaborating on a still-unreleased recording featuring Joe Walsh and his mentor Glenn Schwartz, who both turned up as surprise guests on Saturday. Walsh introduced the denim-clad Schwartz, 78, as the man who taught him guitar, and the elder musician took centerstage to immediately begin shredding. (Schwartz quit an early lineup of the James Gang, making room for a then-unknown Walsh to leave his mark.) Schwartz, his long graying hair beneath a bandana, stood between Auerbach and Walsh as their trio of guitars raged and snarled. Auerbach and the band were also joined by three members of Mariachi Flor de Toloache on backing vocals, but it was the striking appearance of the ecstatic aging guitarist unhooking one supercharged riff after another that will be remembered the longest.
