Power is the tenth studio album by American rock band Kansas, released in 1986. A year and a half after Kansas disbanded at the end of the Drastic Measures tour, former lead singer Steve Walsh returned to revive Kansas along with original band members Phil Ehart and Rich Williams. Guitarist Steve Morse, who joined at Ehart's invitation after the two met at a concert in Atlanta, became significant in the new lineup. Bass guitarist and vocalist Billy Greer (who had worked with Walsh in the short-lived band Streets after he left Kansas in 1981) completed the lineup, which began rehearsing in July 1985 while Walsh was finishing up a tour as sideman for Cheap Trick. They released Power the following year.
