It feels like a lifetime ago when Lady Gaga, in the darkest days of the pandemic, released “Chromatica” in May 2020.It was essentially, a way to free yourself from the lockdown of the walls you were climbing and escape to another planet where the clubs were still pumping out beats—instead of hand sanitizer—in a world where masking up and social distancing never existed.But perhaps Chromatica was a victim of timing: There was only so much an album designed to just dance could do when there was no place to dance.And as if “Chromatica” never happened—aside from the futuristic getup that, for Gaga, almost looked like grocery-shopping sweats at this point—she came out strong at the Chromatica Ball at MetLife Stadium on Thursday night with three of her biggest pre-Covid hits: “Bad Romance,” “Just Dance” and “Pokerface.”Bam. Bam.
