In the twisting saga of Cardi B and Offset, the actual music often seems tangential. Gossip magazines and distinguished newspapers alike have breathlessly covered the roller-coaster relationship of the two chart-topping rappers: her pregnancy reveal, his onstage proposal. Her accusations of his infidelity, her breakup. His bouquet-wielding apology, their Grammys reconciliation. Taken as a whole, the many headlines form a narrative that adheres to well-worn celebrity archetypes: Offset as the vapid, carefree lothario, taken back in by Cardi, the forgiving, world-weary mother. But on consecutive days this week, each rapper released songs that complicate any two-dimensional perception of their relationship.
