Enough already with the Harlem Shake. According to dancing.org, the Lindy Hop is "the authentic Afro-Euro-American Swing dance," and its evolution through the first half of the 20th century moved directly through Harlem — decades before its now-memed successor. And it's continued to move: Today, you can find Midwest Lindyfests, Denver's annual Lindy on the Rocks, and even classes at Movement Arts Community Studio (525 E. Fountain Blvd., #150, movementartscs.com). Under the title of Progressive Blues, tonight's class begins at 8:30 and costs $15, though you can spend $30 and sign up for a series. — Kirk Woundy
