Katok i Skripka (The Steamroller and the Violin) was the last short Andrei Tarkovsky directed before moving on to his first feature. The film tells a very simply story of friendship between an artistic, sensitive seven-year-old violinist named Sasha and a physical, blue-collar steamroller operator. They befriend each other after Sasha is threatened by some ruffians, spend the day together, and alter each other's perceptions of life.
