Greta Van Fleet are known for bringing a powerful stage show – even when the power gets shut off, apparently.

The band was performing in Boise, Idaho on Saturday when the power suddenly went out.

Fans quickly lit up the arena with their cell phones, while the band improvised – since their instruments were no longer amplified, they gathered around the drum set for an impromptu four-way drum solo.

The band shared a clip of the moment on Twitter, writing “When the arena goes dark, the show must go on! Thank you for lighting up our night, Boise!“
