Lindsey Stirling’s current Shatter Me tour visited San Francisco for two sold-out shows at The Warfield (May 16/17). The show began with dramatic drum beats as the violinist bowed behind a sheer curtain that reached the ceiling. Taunting the crowd for several minutes, her wraithlike silhouette was visible on a raised platform illuminated by a large circular video screen. When the curtain finally lifted, the classically trained violinist erupted into the fitting song “Beyond the Veil.”
