Chester and Joe performed two songs, both with pre-recorded live instrumentals (and in the case of "Burn It Down", Mike's live vocals).
There were several problems on "Burn It Down". Joe messed up the intro, Chester messed up the lyrics to the second verse, and somehow a kick drum came in too early before the first chorus.
Other Notes
The event was titled "Mercedes-AMG Driving Performance Award and All New Mercedes-AMG C63 Coupe China Launch Ceremony." Chester and Joe's appearance was a surprise to those in attendance and was unannounced beforehand.
Linkin Park crew members Jim Digby (tour manager) and Tater (monitor engineer) went to China to assist Chester and Joe with this performance.
