In a Dark Wood, a film about Mathew Rosenblum's Lament/Witches Sabbath by Pittsburgh filmmaker David Bernabo will premiere at the Pittsburgh JFilm Festival on Monday, April 30th! In a Dark Wood charts the path of the composer's Lament/Witches’ Sabbath, a highly personal concerto written for world famous clarinetist/composer David Krakauer. Filmed in Pittsburgh, New York City, and Boston, the film reminisces on the friendship of Rosenblum and Krakauer while exploring Rosenblum’s remembrance of his grandmother, who fled Proskurov, Ukraine in 1919, ahead of a massacre. This moving documentary tells a story of the endurance of family, the winding path of friendship, and the craft of composing music.
