Carey performed a medley of her 1990 debut single "Vision of Love" with "Infinity" as part of its promotion, the first time being at the 2015 "Billboard" Music Awards on May 17, 2015, her first appearance at the awards show in seventeen years. A video tribute to the singer was shown prior to the singer entering the stage, who was wearing a "sheer and glittery" dress. Andrew Hampp for "Billboard" noted that it was an "Octave-leaping" performance and one of the most memorable of the night. However Carey's vocals, despite confirming that she had been suffering from bronchitis prior to the performance, garnered a mixed reaction from users on Twitter. D’Addario wrote that she sang "Vision of Love" with "evident confidence", but noted that the key had been lowered. The next day, Carey repeated the medley on "Jimmy Kimmel Live!".
