Zoe C. Sherinian shows how Christian Dalits (once known as untouchables or out castes) in southern India have employed music to protest against social oppression and as a vehicle of liberation. Her focus is on the life and theology of a charismatic composer and leader, Reverend J. Theophilus Appavoo, who drew on Tamil folk music to create a distinctive form of indigenized Christian music. Appavoo composed songs and liturgy infused with messages linking Christian theology with critiques of social inequality. Sherinian traces the history of Christian music in India and introduces us to a community of Tamil Dalit Christian villagers, seminary students, activists, and theologians who have been inspired by Appavoo's music to work for social justice. Multimedia components available online include video and audio recordings of musical performances, religious services, and community rituals.
