Barclays Center, Brooklyn

The Boy Is Mine pair were joined by guests such as Kelly Rowland, Fat Joe, Ciara and Tyrese for a sometimes strange, sometimes soaring throwback night

Supposedly feuding for over 25 years might be bad karma, but it’s great for ticket sales. Of course, Brandy and Monica aren’t actually fighting, they just did such a good job of pretending to hate each other on their 1998 duet The Boy Is Mine that the world has been convinced of it ever since. The R&B legends have taken pains to point out that their relationship is harmonious in multiple interviews leading up to this 32-date co-headline tour, even making fun of the drama in a recent Dunkin advert that featured them fighting over a frappe.

Happily, Brandy and Monica’s sisterhood also means they’re playing their biggest venues in decades. After emerging on stage from a vintage elevator wearing sunglasses and scowling expressions, the duo launches into a kind of sing-and-dance-off, trading places and performing a trio of classics apiece as the other watches with disdain. It’s a knowing nod to their purported rivalry that begins to take on the feeling of a variety segment, which isn’t helped by the trimming of songs like What About Us? and Like This and Like That to 90 seconds apiece. Even so, their camaraderie shines through as Brandy quickly breaks character to sway and sing along to Monica’s Don’t Take It Personal (Just One Of Dem Days), a showcase for her slightly raspy, soulful vocals during which she winds her hips and aims gun fingers at the audience.
