Mariah Carey Revisits Her Greatest Eras During Iconic Performance

Fans at T-Mobile Arena erupted with cheers from the minute Mariah opened the show with her classic "Fantasy." She continued with an upbeat mashup of her hits "Honey" and "Heartbreaker" before she slowed it down for a soulful rendition of her 1997 ballad "My All." She then moved on to her 2000s hits like "Touch My Body" and "Obsessed," and midway through her set, she performed her recent single "Type Dangerous" from her upcoming album, Here For It All, which is set to drop next week.
