ck is the seventh studio album by American R&B/funk singer Chaka Khan, released on the Warner Bros. Records label in 1988. ck was Khan's first album not to be recorded with Arif Mardin, instead it had with the exception of two tracks Russ Titelman at the helm as producer, with whom she had collaborated on hits like "Ain't Nobody" (1983), "Eye to Eye" from 1984's platinum-selling I Feel for You as well as "Tight Fit" from her previous album Destiny. Musically ck combined a variety of genres such as soul, R&B, funk, pop as well as two jazz titles and altogether the set was more laid-back, less hip-hop influenced and production-wise not as complex and synth-driven as I Feel for You and Destiny.
