Serj Tankian Performs at Game of Thrones Concert

System of a Down lead vocalist Serj Tankian made a special guest appearance at the Los Angeles "Game Of Thrones: A Live Concert Experience" at the Forum in Inglewood, California. The singer delivered a rendition of "The Rains Of Castamere", a fictional ballad from Westeros

The 28-city tour features the wildly popular HBO TV show's music performed by an orchestra and choir.

"In an abstract way, we're re-creating moments from the show on the stage," the concert's creator and conductor, Ramin Djawadi, told the Los Angeles Times. "The musical themes are almost characters on their own — there's the Daenerys theme. The Dragon's theme. The Stark theme. It brings a whole other level of emotion that’s so much more than just us playing songs from the show."

Djawadi, who created the music for all of the seasons of "Game Of Thrones", also composed the music for feature films such as "Iron Man" and "Pacific Rim" as well as HBO's "Westworld".
