The Game of Thrones concert experience kicked off on February 20th in Minneapolis and concludes next Sunday, April 2nd in Portland, OR. The concert brings the HBO hit series to life, incorporating its music performed by an orchestra, choir, and guest vocalists on seven stages representing the seven kingdoms of Westeros. Visual enhancements projecting highlighted footage of the show’s storyline are screened amongst the music making it a thrilling experience.

System of a Down frontman Serj Tankian was seen during last night’s performance in Los Angeles at the Forum as a special guest. Tankian didn’t have his pogo sticks nor any appetizers as he stunned the crowd with a powerful performance of “The Rains Of Castamere.”

Check out the footage below:

Tankian hinted at this a few days prior on his Twitter while playing cars with Game of Thrones composer Ramin Djawadi:
