Input: "Grey" is the fourth studio album by Sandy Lam, released under CBS Records in 1987. To continue the success of her last album in February of the same year, Sandy and her producers focused on the successful elements of her last album and applied onto this album, which introduced Eurodance into Hong Kong. Through this album, Sandy has proved herself not as a one-hit-album wonder, but a determined singer who can always create breakthrough in her albums and performance. "Grey" was released very strategically by CBS Records. They were named Grey Project Phase 1, 2, and 3 respectively. Phase One showed Sandy looking directly at the audience, and the clothing and background was cream-white. Phase One was released in vinyl, cassette tape and CD. Phase Two showed Sandy looking at the audience at the corner of her eye, in which the background and clothing were mainly dark blue and black. Phase Two was released only in vinyl and cassette tapes. In Phase Three, Sandy showed no demand from the audience. She was in stark black and white. Like Phase Two, Phase Three was only released in vinyl and cassette tapes. Phase Three was a 12 inch remix of "Grey" and "Family Man". Question: "Grey" is the fourth studio album by a singer born in which year ? Answer: 1966
Output:
Grey is the fourth studio album by Sandy Lam, released under CBS Records in 1987.
