What is there left to be said about Frankie Knuckles, the Godfather of House, that hasn't already been said? The guy basically invented house music -- playing at Chicago's "The Warehouse" in the 80s and prompting people to go looking for "that 'house sound" on Sunday morning after one of his sets. That's where the word came from -- house music all night long ... get up!
There are soooooo many good sets by the man floating around the internet these days. I've danced to his tunes many times. A lot at the Ministry of Sound in London in the early 90s. Then, a crazy rave party in the Docklands in Melbourne in the late 90s where he DJ'ed a laaaate set of disco classics. Also caught a set of his at the Prince Of Wales with my dance buddy Shauno in the early 2000's.
The guy was born in 1955. He's probably older than your dad. And yet, he's still out there playing tunes to the gay massive! Here's a great set of his from a couple of years ago that I know you'll love.
