Ron Hardy was the DJ of Chicago club the Muzic Box. He was instrumental in the developement of House_music.

In 1983 the Muzic Box club opened in Chicago. Robert Williams owned it, but yet again the driving force was a DJ, Ron Hardy. Hardy always opened his set with "Welcome to the Pleasure Dome" but the chief characteristics of the club's sound were sheer massive volume and an increased pace to the tunes. The volume is self-explanatory, the pace was apparently the result of Hardy's heroin use. The club also played a wider range of music than just disco. Groups such as Kraftwerk and Blondie were well received, as was a brief flirtation with punk, dances like "Punking-Out" or "Jacking" being very popular.
