jackrabbit. is the Americana-tinged country band co-led by actor-musicians Dermot Mulroney and his brother Kieran Mulroney. Cowriting and performing together, the brothers blend twangy guitars, layered harmonies, and emotion-rich lyrical storytelling to create what they term a “Cali-Country” vibe—drawing inspiration from the Bakersfield sound, the Eagles, and the soft-rock tradition of California’s Sunset Strip.
