The Pretty Reckless' tour stopped in Seattle Wednesday, and the show featured a surprise guest befitting of the grunge capital.

Soundgarden guitarist Kim Thayil joined Taylor Momsen and company onstage during the concert to rock the TPR track "Only Love Can Save Me Now" as well as the Soundgarden song "Loud Love."

Momsen posted a photo and video clip of the live collaboration on Instagram along with a caption thanking Thayil.

"I'm once again humbled to share the stage with you my dear friend, what an amazing human being," Momsen wrote.

The studio version of "Only Love Can Save Me Now," which appears on the new Pretty Reckless album Death by Rock and Roll, also features Soundgarden and Pearl Jam drummer Matt Cameron. Momsen, who's a big Soundgarden fan, previously performed with Thayil, Cameron and bassist Ben Shepherd at the 2019 Chris Cornell tribute concert.
