KUUMAA emerged in 2016, after which its Helsinki-based members recorded their first demo, “Hulluista runoista,” which secured them a contract with the major music label Universal Music Group. This milestone marked the beginning of work on the band's debut studio album, produced with the assistance of Jonas Olsson and Joonas Parkkonen. The self-titled debut full-length record, KUUMAA, was released in April 2019 and peaked at number ten on the official Finnish albums chart.
The band continued working on new material, and their subsequent tracks, “Oo vielä sekunnin mun” and “Tulipalo,” achieved massive popularity in their home country. In January 2023, it was announced that KUUMAA would participate in Uuden Musiikin Kilpailu (UMK), the competition determining Finland's representative for the Eurovision Song Contest.
They entered with the single “Ylivoimainen,” which shot straight to number one on the official Finnish charts upon release. Despite its commercial success, they finished fifth in the UMK final, scoring a total of 107 points. Nevertheless, this did not stop them from winning the “Band of the Year” category at the 2023 Emma Gaala awards.
