The album title is named after the defunct theme park Six Flags AstroWorld, which was located in Houston, Texas prior to its closure. Scott, a Houston native, aimed for the album to sound like "taking an amusement park away from kids". He also described the album as a continuation of his debut album Rodeo (2015).

The album was supported by four singles, "Butterfly Effect", "Sicko Mode", "Yosemite", and "Wake Up".
