About this piece

“Border Lines” is a reflection on the immigrant experience, drawing on the rhythms and melodies of Central American folk music to showcase themes of displacement, empathy, and shared humanity. Featuring text by Afro-Latina poet Yesenia Montilla, the piece challenges the artificiality of borders and calls for unity across cultures. Please refer to the description accompanying the YouTube video for additional information.
