Hard Skool appeared in October 2021 as a Guns N' Roses single, another track left over from the Chinese Democracy sessions and finished by the line-up of Axl Rose, Slash, and Duff McKagan. It is a solid rocker built on a riff that reaches back to the band's early work. The B-side is a live version of Absurd, the song the band had returned with a few months earlier. This edition is a limited edition 7-inch single.
