Haviah Mighty’s 2019 album, 13th Floor, earned her the Polaris Music Prize, elevating the MC/producer from Toronto secret to Canadian treasure. But with her follow-up mixtape, Stock Exchange, she’s ready to take on the world. And that speaks as much to her relentless bravado as to the international cast of collaborators she corrals across 12 tracks that blur the line between the personal and the political. British rapper Yizzy adds some grime flavor to “Protest” as he commiserates with Haviah over being racially profiled by police, while North Carolina MC Jalen Santoy brings Southern heat to the tropical-trap anthem “Way Too Fast,” a celebration of Black excellence against all odds. But Stock Exchange’s fiery polemics are balanced out by more playful odes to being your own girlboss, like the Mala Rodríguez-assisted reggaetón romp “Flamenco” and the saucy ’90s-style jam “So So,” featuring a show-stopping cameo from Brooklyn rapper Dai Burger.
