Brazilian pop singer Luísa Sonza made her Tomorrowland Belgium debut on 24 July, joining Dutch duo Kris Kross Amsterdam to perform “My Oh My” live for the first time. The appearance placed Sonza on one of the festival’s major stages and highlighted her growing international profile.

The performance took place at 5 p.m. local time on The Great Library stage, during Kris Kross Amsterdam’s electronic set. “My Oh My” was made with French singer-producer Willy William after he and the duo met at the Q Music Awards; Sonza was invited to provide the vocal, bringing a pop element to the track. Sonza said she was honoured to represent Brazilian pop at a festival attracting attendees from more than 200 countries.
