The POP Montreal festival will celebrate its 10th anniversary with a major event. On Thursday, September 22, Arcade Fire will perform a free outdoor concert at Place des Festivals, with Karkwa serving as the opener. The group’s Régine Chassagne shared her thoughts in a statement: “Our band couldn’t exist without Montreal. After having had the chance to tour extensively around the world, we’re very excited to finally come home. And to do so the Montreal way, we hoped to play a free outside show, on the very last day of summer as a big ‘Thank you’ to the beautiful city we love so much.” The performance will be broadcast live on SiriusXM Canada.
