Spiritbox’s Courtney LaPlante joins Illenium onstage at Sphere residency

Before Metallica takes the stage at Sphere in October, Courtney LaPlante tested how the high-tech Las Vegas venue handles heavy metal.

The Spiritbox frontwoman made an appearance during DJ and producer Illenium’s ongoing Sphere residency. She joined him onstage for a rendition of their 2022 collaboration, “Shivering.”

You can watch footage of the joint performance now via Illenium’s Instagram.

Illenium’s residency supports his latest album, ODYSSEY, which includes a feature from Bring Me the Horizon.

This isn’t the first time LaPlante has joined a cross-genre collaborator for a surprise live performance. She previously joined rapper Megan Thee Stallion at Coachella 2025 to debut their track, “TYG,” live.
