“I feel like I don’t owe apologies,” Brazen Barbie declares on “DEEP END,” the second track on her debut mixtape, BRAZEN. At just 19, the Australian artist radiates confidence sharp enough to cut through any hater’s perception. Sure, she can craft club-ready singles like “Ain’t No Dummy,” or lean into her playful side on “Sneaky,” but there are subtle, reflective moments present as well. On “What Do I Care,” she’s processing betrayal, turning pain into fuel for her ambition. In all, BRAZEN plots what sounds like a very probable ascent for the MC, pairing a pronounced rhyme style with vulnerability and bravado. Or as she puts it on “Doomsday,” Brazen Barbie is “the calm and the storm.”
