Charles Watson and Rebecca Taylor are Slow Club. After four well-received albums and 10 years of touring, conflicting perspectives on success have pushed the two apart. Could this be the end of the Sheffield-based indie band? With intimate access to what may have been the band’s final tour, filmmaker Piers Dennis joined Charles and Rebecca on the road, capturing the frailties and brilliance of their musical partnership and documenting what friendship looks like from the back of a bus. Unflinchingly clear-eyed, it captures not only the camaraderie, elation, fretfulness and boredom of road life, but also the moments that the big existential questions – ambition, artistic purpose, emotional vulnerability – appear. A remarkable, bittersweet portrait.
