Smallcreep's Day is the first studio album by English guitarist and songwriter Mike Rutherford, released in February 1980 on Charisma Records. It was recorded in 1979 during a period of inactivity from his rock band Genesis, during which Rutherford and keyboardist Tony Banks recorded their first solo albums. The 24-minute title track is based on the 1965 novel Smallcreep's Day by Peter Currell Brown which tells the story of Mr. Smallcreep and the journey of self-discovery he takes through the assembly line of the factory he has worked in for forty years.
