Vessel of Sleep Token performs during Day 3 of Leeds Festival 2023 at Bramham Park on August 27, 2023 in Leeds, England. As Franck tells ABC Audio, the tour allowed him to meet Sleep Token’s mysterious, anonymous frontman, known publicly only as Vessel. “I enjoy him very deeply as a person.”Like Sleep Token, Bilmuri combines elements of many different genres to create their sound. To that end, Franck likens Bilmuri’s role in a Sleep Token show to comic relief in a dramatic movie. Sleep Token’s tour continues Tuesday in Lincoln, Nebraska.
