Carolina Durante signed a joined contract in 2017 with Sonido Muchacho and released their first EP titled "Necromático" on December 23 which was well received by the critics. In March 2018 the band released their first hit single 'Cayetano' which caused major controversy due to its explicitly and naming of the main politic parties in Spain. The song earned the band a Premio MIN for 'Song of the Year' and another one for 'Best New Artist. In November 2018 the band released a more pop track titled 'Perdona (Ahora Sí Que Sí)" alongside Amaia, who won the ninth edition of the very well-known Spanish musical talent competition Operación Triunfo. This one is the one who opened them the doors to a major national popularity. However, "Perdona" is not an original song but a cover of Marcelo Criminal's. Thus, the band released their debut studio album, which they called "Carolina Durante", on April 26, 2019 and premiered with four secret shows in Madrid, Valencia, Barcelona and Seville. The album debuted at the second position of the PROMUSICAE chart, lasted on it for 25 consecutive weeks and was named the best Spanish album of 2019 by specialized portals like "El Cultural". In May they started a festival tour that visited many festivals like the Benicàssim International Festival, Dcode, Low Festival or Donostia Festibala. In November they started their first solo tour that visited Spain, London and Berlin. They performed at the 2019 United Nations Climate Change Conference in Madrid. In March 2020 the tour stopped due to the 2020 coronavirus pandemic.
