In 2018, Carey signed a worldwide deal with Live Nation Entertainment. The first commitment out of the deal was her new Las Vegas residency, The Butterfly Returns, which was launched in July 2018 to critical acclaim. Its first 12 shows in 2018 grossed $3.6 million, with dates later extending into 2019 and 2020. Following the residency, Carey embarked on her tour in Asia and returned to Europe with her concert series. While on tour, a representative from Sony Music Asia Pacific presented Carey with a certificate for achieving 1.6 billion sales units in Asia Pacific. In September 2018, Carey announced plans to release her fifteenth studio album later in the year. The project was announced alongside the release of a new song titled "GTFO", which she performed on September 21, 2018, when she headlined the 2018 iHeartRadio Music Festival. The album's lead single, "With You", was released in October and performed for the first time at the American Music Awards of 2018. The single became Carey's highest-charting non-holiday song on the US Adult Contemporary chart since "We Belong Together", and the third highest-charting song of her career on the Adult R&B Songs chart. A second single, "A No No", was released in March 2019 and peaked at number 17 at US R&B Digital Song Sales. The album, titled "Caution", was released on November 16, 2018, and received universal acclaim from critics. "Caution" was described as a "fine-tuning" of Carey's previous work and was praised for its freshness which made it "pleasingly defiant." By December 2018, the album had been featured on numerous year-end lists by music critics and publications.
