During a recent show in Mexico City, Feist took to the stage in support of her recently released album Metals. While on stage, Feist and her band performed a surprise cover of Guns N' Roses' classic hit "November Rain." In the midst of the cover, a Slash look-a-like showed up during the song's memorable guitar solo, and all that before Feist absolutely destroys a piñata. Now that's what I call an awesome performance. You can check out all the piñata smashing action in the player above, via Consequence of Sound.
