The second edition of Todo Mundo no Rio, internationally known as Mayhem on the Beach, marked a historic moment on Copacabana Beach. After thirteen years away from the country, Lady Gaga returned to Brazil with a free concert promoting her eighth studio album, Mayhem (2025). With a record-breaking crowd of 2.5 million people, the show became the biggest performance of her career and cemented her as the female artist with the largest audience in history.
