In September 2013, at the peak of the Ceremonials Tour Extended, Florence + The Machine—led by Florence Welch and riding their second album Ceremonials, where baroque-pop with orchestral swells and gothic motifs gained stadium scale—headlined Rock in Rio IV in Rio de Janeiro, the legendary festival founded in 1985 by Roberto Medina drawing 100,000 to Cidade do Rock. The 90-minute set, brimming with dramatic vocal surges and choral refrains, embodied the Latin American leg's climax, where "Spectrum" resonated through the crowd, transmuting the Brazilian night into a cathedral of collective catharsis under tropical skies. As a rare artifact of their global triumph, this show underscored Florence's role as a modern shamaness, infusing rock with ritual scale.
