Jamie Campbell Bower, who plays the evil Upside Down monster Vecna in the fourth season of Stranger Things, has demonstrated the frightful voice he uses for the character by reciting Lizzo lyrics.

Bower claimed that Doug Bradley's portrayal of Hellraiser served as inspiration for the low, menacing voice that his character uses throughout the show while appearing on The Tonight Show Starring Jimmy Fallon. He said, "It kind of says that this deep, booming voice comes out of the darkness. “I loved it." It was amazing. And I’m a singer, so I kind of just relaxed myself, relaxed my larynx. "

Fallon asked Bower to perform his Vecna voice later on in the interview by having him recite words that his character would never use. This included Kate Winslett's famous Titanic line, "Jack, I want you to draw me like one of your French girls," and Julia Roberts' "I'm just a girl, standing in front of a boy" line from Notting Hill.

However, Bower ended by delivering a few lyrics from Lizzo's song "About Damn Time" that were distinctly uncharacteristic of Vecna. Bower says in a commanding, gravelly voice, "In a minute, I'm going to need a sentimental man or woman to pump me up." I'm trying to bring out the fabulous while feeling fussy and walking in my Balenci-ussys. Watch it below – the segment starts around the five-minute mark.

Campbell was partly appearing on The Tonight Show to promote his forthcoming solo single "I Am," which is set to arrive on August 21. The actor and musician has been in numerous bands throughout his life, but told NME last year he was enjoying the freedom of being a solo artist.

“I feel creatively in the best space that I’ve been in for a long time, if ever,” Bower explained at the time. “There is certainly something to be said for just going with your gut and going with intuition.”

In June, Bower revealed he listened to Placebo’s cover of "Running Up That Hill (A Deal With God)" to help him get out of character after playing Vecna. The original Kate Bush version of the song appeared prominently throughout the fourth season, and experienced a huge resurgence in popularity as a result.

Last month, the actor and musician opened up about his experience of addiction, celebrating seven-and-a-half years of sobriety. I have made many mistakes in my life. But each day is a chance to start again. Atone for mistakes and grow, "the Bower wrote on social media at the time.
