Narbutienė organized the musical program of the Thomas Mann Festival in Nida from its inception in 1995 until 2007. The summer festival, under her sponsorship, was dedicated to topics such as Thomas Mann and Richard Wagner (1998), Thomas Mann and the myth (2000), and Thomas Mann and the North (2001). The programs combined concerts, readings, exhibitions, theatre performances, and film screenings. She described the festival's concept as revolving around the connections of Thomas Mann to music. She also contributed to the inclusion of song and dance celebrations in Estonia, Latvia, and Lithuania in UNESCO's Masterpieces of the Oral and Intangible Heritage of Humanity.
