C.J. & Co. was a prominent American disco group active during the late 1970s. Known for their dance-oriented music, they were led by the talents of Curtis Durden, Joni Tolbert, and Cornell Stone. Their 1978 hit single, "Devil's Gun", a fusion of funk, soul, and disco was distinctively noted for being the first record played at Studio 54, an iconic New York City nightclub. This key contribution has solidified their place in the annals of disco music history.
