Sadly my story -- that of a Cincinnati native who didn't even know King Records existed until I moved elsewhere -- isn't an unusual one. While living in Kansas City in 1996 I saw a DJ play nothing but King Records singles for two hours straight.
It was all stuff like this:
King Records recordings are now played regularly by the DJ's on medium-wattage WNKU, but otherwise they continue to wallow in obscurity, as does the King Records building itself.
Do yourself a favor and type "Cincinnati King Records" into the Youtube search bar and spend some time getting to know the seemingly endless number of killer tracks recorded 30 feet from I-71 in Evanston.
