The Hustle is one of the most common line dances done throughout the world. Today it mostly refers to the unique partner dance done in ballrooms and nightclubs to disco music. It has some features in common with swing dance. Its basic steps are somewhat similar to the Discofox, which emerged at about the same time and is more familiar in various European countries. In the 1970s there was also a line dance called the Hustle—which is regaining popularity as people throw 1970s theme parties or schools have 1970s dance performances. Modern partner hustle is sometimes referred to as New York Hustle.
