In celebration of Warped Tour’s 20th anniversary, Linkin Park showed up for a surprise performance in Ventura, California. During their performance, the band were joined onstage by members of Yellowcard, A Day To Remember (which is awesome, because ADTR aren't even on Warped this year), Issues, the Devil Wears Prada, Finch and Breathe Carolina.
