When Henry Alford wrote about his experience with a Zumba class for The New York Times, little did he realize that it was the start of something much bigger. Dance would grow and take on many roles for Henry: exercise, stress reliever, confidence builder, an excuse to travel, a source of ongoing wonder, and-when he dances with Alzheimer's patients-even a kind of community service. Tackling a wide range of forms (including ballet, hip-hop, jazz, ballroom, tap, contact improvisation, Zumba, swing), Alford's grand tour takes us through the works and careers of luminaries ranging from Bob Fosse to George Balanchine, Twyla Tharp to Arthur Murray. Rich in insight and humor, Alford mines both personal experience and fascinating cultural history to offer a witty and ultimately moving portrait of how dance can express all things human.
