The album capitalized on the popularity of the Spock character on Star Trek. The songs contain many outer-space elements, science fiction-themed narrations, and space sound effects. Opening with a rendition of the show's main theme, the album also features a take on the theme to Mission: Impossible, which Nimoy would incidentally go on to join as a cast member in 1969. Also featured is an instrumental version of the song "Beyond Antares", written for the Star Trek episode "The Conscience of the King" and originally sung by Nichelle Nichols. Nimoy sings two show tunes, "Where Is Love?" (from Oliver!) and "Lost in the Stars" (from the musical of the same name). Closing track "A Visit to a Sad Planet" is a spoken word science fiction piece that was released as a single and charted at number 121 on Billboard.
