He was a husband, a father, a preacher - and the preeminent leader of a movement that continues to transform America and the world. Now, in a special program commissioned and authorized by his family, here is the life and times of Martin Luther King, Jr. Featuring King's I Have a Dream Speech.

Listen "live" to one of the most iconic orators of all times in this packed-full collection of Martin Luther King Jr. speeches.

A world in which a handful of panicky survivors choose sides - or are chosen.
