Aespa recently held their second "Synk: Parallel Line" concert in Seoul, marking the beginning of their world tour. The two-day event at Jamsil Indoor Stadium drew in around 12,000 attendees. The quartet kicked off the concert with high-energy performances of "Drama," "Black Mamba," and "Salty & Sweet," dressed in striking black attire. They later transitioned to a more extraterrestrial vibe with "Supernova," followed by a sensual mood during "Mine" and "Illusion," which featured intricate metal structures. The group also showcased their emotive vocal abilities through B-sides "Thirsty" and "Prologue." The highlight of the concert was the solo performances, with Giselle, Karina, Ningning, and Winter each presenting previously unheard songs. The group then switched to hip-hop attire for lively performances of "Spicy" and "Licorice," engaging the audience to join in the fun. The concert concluded with a surprise appearance by Naevis, SM's first virtual artist, and a captivating performance using a 3D screen. Aespa returned to the stage in mysterious outfits, closing the show with their unique style in songs like "Next Level" and "Armageddon." The group performed for approximately three hours, delivering a total of 26 songs, including four solo performances per member and three encore performances. Karina expressed gratitude to their fans, acknowledging their support as they continue their world tour across Asia, Australia, and plans for expansion to North America and Europe in the coming year.
