By now, you've probably heard the news: On Tuesday, Mar. 31 2014, Frankie Knuckles, the progenitor of Chicago house music, died at the age of 59. In the late-'70s, his unique sets, played at an after-hours club called the Warehouse, gave house both its aesthetic form and name ("house" originally referred to the kind of music Knuckles' played at his club). His potent mixture of disco and electronics is still a large part of global dance culture today -- house music soundtracks parties in nearly every major city in the world. The suddenness of his death was a tragedy, but that doesn't mean you should stay depressed. Instead, we recommend you go out and celebrate his life at one of the many parties that have chosen to honor his legacy.
