However, Davis expressed disinterest in buying the record company and thus sold the record label to PolyGram earlier that year. PolyGram, a European conglomerate that was buying up US record labels as fast as they could make deals, immediately shut down the label and had all of its artists' contracts and reissues (including Mills') transferred to their Casablanca imprint, which they had owned since owning 50% of the company in 1977.[3] (PolyGram bought the other 50% in 1980, the same year Mills recorded the LP Sweet Sensation).[4]
