Stjepan Hauser, a Croatian cellist, performs “Nessun Dorma” in a forest with a group of young musicians in this heartwarming music video. I’m sure these young musicians will always have fond memories of this wonderful day spent making beautiful music. Nessun Dorma (Italian for “Let no one sleep”) is an aria from the final act of Giacomo Puccini’s opera Turandot and one of the best-known tenor arias in all of opera.
