System Of A Down headlined Sick New World, the nu-metal festival that took place yesterday on the Las Vegas Festival Grounds. They trotted out some songs they hadn’t performed in a while, doing “Bubbles” and “CUBErt” for the first time since 2015, “Kill Rock ‘n Roll” for the first time since 2017, and “Innervision” for the first time since 2019. Check out video of most of that below.
