Lights Out is the sixth studio album by the British rock band UFO, released in May and also on October 11, 1977 (see 1977 in music). All songs are band originals except for "Alone Again Or" which is a cover of a song by the band Love.
The album was UFO's first to feature lush string arrangements alongside more complex song structures than their previous albums. Producer Ron Nevison brought in Alan McMillan to handle the string and horn arrangements. The most notable song to feature the orchestral coloring was "Love to Love" which became one of the bands most successful singles.
