Whether they’re your nemesis or closest ally, today is National Sibling Day. In honor of that, we’re getting down with Infinity Song , a band of four brothers and sisters based in NYC. Homeschooled musically and academically by their parents alongside their five other siblings, the band’s folks extended their love to found the Boys & Girls Choirs of Detroit. Jay-Z signed Infinity Song to his Roc Nation label in 2016, and wisely advised them not to conform to the label’s artistic culture and instead have the label catch up to them, which led to their 2020 album debut. Metamorphosis, their new EP, contains the tongue-in-cheek track “Hater’s Anthem.”
