I don’t know what it is about the hip-hop business that makes a new album so often take years longer than planned to see the light of day. I get it that leaks can screw with a label’s marketing efforts, and I always hear about how artists want to make sure everything is perfect—on Tuesday Chicago’s Kid Sister is releasing her debut album, Ultraviolet, after nearly two years of delays, much of which she spent tweaking its mixes and redoing its track list. Still, it’s a pop record—when perfection takes that long, it can’t be helping an artist’s career. I mean, I’ve been waiting for the second album by the great Chicago MC Diverse for six years now, but I’m not sure how many other fans are still holding out.
