Rich with over fifteen professional seasons, QW4RTZ embarks on its final lap. Full throttle, the four teammates put everything into a new racing spectacle. Trad, pop, folk, rock, classical—all styles are injected into their four a cappella cylinders. With their always well-oiled vocal mechanics, the group negotiates each turn of this last straightaway with flair. Still guided by their chief engineer Serge Postigo, the four childhood friends surpass themselves once again, delivering top-notch numbers without skidding… or almost. Their a cappella formula allows Louis, Phil, François, and Fa2 to never curb their imagination, proving that even without guitars, they have plenty under the hood.
