WARNING: This slideshow contains photos of Young the Giant's "lightning strobes." Attendees were also advised of the phenomenon on Sunday night through multiple signs posted on the Culture Room's walls. No word yet whether the seemingly spasmatic jumping and flailing of the show's opening band, Grouplove, was a result of strobe induced seizures, or simply an electric performance.
