Argentine singer María Becerra delivered a defiant, well-received performance at Madrid's Noches del Botánico festival, held just five days after Spain beat Argentina in the World Cup final. The match's aftermath had spilled into a heated online row between Spanish and Argentine fans, intensified when Becerra wrapped herself in the Argentine flag and waved it on stage at the opening night of her Spanish tour in Barcelona, prompting mixed reactions from onlookers.

The Madrid concert itself was further overshadowed by wildfires blanketing the city in smoke and triggering air quality warnings, raising doubts over whether the show would go ahead at all. Despite the tension and hazardous conditions, Becerra performed a set mixing choreographed numbers with pop ballads, welcomed guest appearances from Spanish singer Abraham Mateo and Chilean artist Katteyes, and shared intimate moments with fans, including stepping off stage during "Tatú" and inviting an audience member to duet on "7 vidas".
