Macklemore has launched a 'Free Palestine' tour in Dublin featuring collaborations with Hozier and Kneecap, drawing both acclaim and controversy amid political backlash and a UK ban attempt by 50 peers. The tour has sold out, prompting reactions from figures like Jack Antonoff and Brian Eno, who criticized Ed Sheeran's handling of the situation, while other artists including Lorde and Zach Bryan have shown solidarity with the cause.
