QW4RTZ, with fifteen professional seasons under their belt, embarks on their final lap. The four vocalists go full throttle in a new racing-themed show. Blending trad, pop, folk, rock, and classical styles into their a cappella engines. With finely tuned vocal mechanics, they navigate every turn of this last stretch with style. Guided by chief engineer Serge Postigo, childhood friends Louis, Phil, François, and Fa2 push their limits, delivering peak performances without skidding... almost. Their a cappella approach unleashes boundless imagination, proving they pack power without instruments.
