TWICE brought an infectious energy to the City of Champions on their This Is For World Tour, playing their first-ever show in Boston and filling TD Garden from the balconies to the pit. Synchronized light sticks scattered throughout the audience turned the crowd into a sky full of stars. The show kicked off with “THIS IS FOR,” “Strategy,” and “MAKE ME GO,” setting the stage for a night of high energy and pure joy. Even with Dahyun and Chaeyoung absent due to an ankle fracture and health issues, respectively, the remaining seven members—along with a small army of backup dancers—turned the arena into a massive dance floor, especially during fan favorites like “TAKEDOWN,” “What Is Love?,” and “Dance the Night Away.” At times, the sheer volume of the arena mix led to some ringing and a loss of clarity in the higher frequencies, though this did little to dampen the energy, especially with ear protection taking the edge off.
