QW4RTZ embarks on its final lap after fifteen professional seasons. Full throttle ahead, the four teammates pour everything into a new racing spectacle. Trad, pop, folk, rock, classical—all styles fuel their four a cappella cylinders. With perfectly oiled vocal mechanics, the group tackles the last straightaway with panache. Guided by chief engineer Serge Postigo, these childhood friends surpass themselves once more, delivering top-tier numbers without skidding… or nearly so. Their a cappella formula unleashes imagination without brakes, proving that even without guitars, they have horsepower to spare.
