They were each born with the gift of gospel.

Martin's voice kept people in their seats, but also sent their praises soaring.
Mahalia's voice was brass-and-butter - strong and smooth at the same time.

With Martin's sermons and Mahalia's songs, folks were free to shout, to sing their joy.

On August 28, 1963, Martin Luther King, Jr. gave his famous "I Have a Dream" speech from the steps of the Lincoln Memorial, and his strong voice and powerful message were joined and lifted in song by world-renowned gospel singer Mahalia Jackson. It was a moment that changed the course of history and is imprinted in minds forever. Told through Andrea Davis Pinkney's poetic prose and Brian Pinkney's evocative illustration, the stories of these two powerful voices and lives are told side-by-side -- as they would one day walk -- following the journey from their youth to a culmination at this historical event when they united as one and inspiring kids to find their own voices and speak up for what is right.
