Set against a volatile political landscape, Irish republican culture has struggled to maintain continuity with the past, affirm legitimacy in the present, and generate a sense of community for the future. 'Lullabies and Battle Cries' explores the relationship between music, emotion, memory, and identity in republican parading bands, with a focus on how this music continues to be utilized in a post-conflict climate. As author Jaime Rollins shows, rebel parade music provides a foundational idiom of national and republican expression, acting as a critical medium for shaping new political identities within continually shifting dynamics of republican culture.
