Pacific Daydream was released October 27, 2017. It is Weezer’s eleventh studio album. They originally set out to make another self-titled darker album known as the Black Album. However, Cuomo said that he started writing songs that did not fit the darker sound, so he started work on a project called Pacific Daydream.
Rivers' original title for the album was “Somebody’s Daydream,” inspired by a piece of Chinese philosophy written by Zhuangzi in which a man has a dream so vivid of a butterfly he is unsure if he is a man dreaming of a butterfly or a butterfly dreaming of a man. It was Patrick Wilson who suggested the change to “Pacific” rather than “Somebody’s.”
