Leftovertureis the fourthalbumbyAmericanrockbandKansas, released in 1976. With Steve Walsh taking a back seat on the production of material, Kerry Livgren stepped up and his compositions retained much of the classically inspired complexity of Livgren's previous work. The album begins with the hit single "Carry On Wayward Son". Kerry Livgren wrote the song as a sequel to the final song, "The Pinnacle", from the previous album, Masque.

Rolling Stone called Leftoverture Kansas's best album to date, and said that it 'warrants Kansas a spot right alongside Boston and Styx as one of the fresh new American bands who combine hard-driving group instrumentation (with a dearth of flashy solos) with short, tight melody lines and pleasant singing.'
