Oidorno, an antifascist Oi! band from Hamburg, Germany, formed in 2015. The group's name combines the music genre Oi! with philosopher Theodor W. Adorno. Their debut performance took place at the Hafenklang live club in Hamburg. In December 2017, they released their first EP, Oi! the EP. Two years later, in April and May 2019, they released the EP Le Roi C'est Moi and the single "Schwarz gelbes Herz", both on the Audiolith label. The EP cover of Le Roi C'est Moi features Adorno seated on a throne made of beer cans and bottles. In August 2019, Oidorno announced a hiatus but returned for supporting acts with Akne Kid Joe in 2022 and performances at the Frühlingsfest des Punkrocks in Bremen and Vienna in 2023. Their song "Auf’s Maul" featuring Destroy Degenhardt reached Number six on Laut.de's charts in 2019. In August 2025, they released a compilation album titled Greatest Hits, which climbed at Number 18 on German Albums chart.
