Ten dancers who took locking, popping, breaking, and house from sidewalks and club floors to the center of global culture. Between the early 1970s and the late 1990s, dancers with no studios, no funding, and no permission invented an entire movement language.

Ten dancers who turned the movie musical of the 1930s to 1950s into the most joyful art form Hollywood ever invented. When sound arrived at the end of the 1920s, Hollywood discovered that the camera could do something the stage never could: put you two feet from a dancer and never let you lose them.

Ten rebels who tore up the ballet rulebook and built a new art form from the body outward, from Isadora Duncan's bare feet to Alvin Ailey's Revelations. Around 1900, concert dance in the West meant one thing: ballet, with its corsets, pointe shoes, and fairy-tale plots.

Ten dancers who carried ballet out of the imperial theaters and into the modern world, from Pavlova's dying swan to Guillem's impossible line. Ballet entered the 20th century as a court entertainment guarded by a handful of imperial theaters and left it as a global art form.

Ten groove architects, from the downbeat of funk to the pulse of the discothèque, who turned the 1970s into one long dance floor. No decade before or since has trusted rhythm the way the 1970s did.

Ten poets with microphones who turned the French popular song into an art form, from the music halls of the 1930s to the concept albums of the 1970s. Chanson is the French word for song, but between the 1930s and the 1970s it came to mean something more particular: a song where the words matter as much as the melody, delivered by a performer who stakes everything on them.

Ten voices, bandleaders, and troubadours who turned a small Caribbean republic into one of the most influential musical nations of the 20th century. Haitian music in the 20th century was never just entertainment.
