Charli XCX dusting off a deep cut from the 'Pop 2' vault for a special live moment is exactly the kind of thing that makes those Brooklyn shows worth the journey. That mixtape was genuinely ahead of its time, and bringing Kim Petras out to revisit it together feels like a proper celebration of where experimental pop was heading back then. It's a reminder that sometimes the best moments happen when artists actually dig into their back catalogue rather than just churning out the hits.
