On September 26, 1998, a video game made its debut in Japanese arcades. It was over seven feet tall and weighed just over 900 pounds. It had no characters, no story, no quests to fulfill or bosses to beat. What it had was a metal platform on which you were supposed to stand, put your feet into the right place at the right time, and dance.

Join two music critics, long-ago players, and Sota Fujimori fans as they take you on the astonishing journey through the artists, influences, and innovators of Dance Dance Revolution, a game two and a half decades in the making and still going -- in homes, arcades, and expos.

From its unexpected appearance to its social heyday to its reappearance in the American market, DDR has taken many forms -- not all of them sanctioned by Konami. It has spawned community, creativity, competition, lawsuits, 1,000+ songs that range from wacky to tacky to beautiful, and yes, a lot of dancing. While we were all leaning on the back bar, working up a sweat, DDR managed to change the world.
