The Bad Nenndorf Boys, a German ska-punk band from Bad Nenndorf near Hannover, was formed in 2000. The group initially released two demo CDs, Alles richtig gemacht and Früher war alles Lauter, before producing their first professional album, Le SKA c'est moi!, in 2005. In 2007, they signed with Sunny Bastards Records and released Wir lügen nicht (2007). In December of that year, the band released the unplugged EP, Anplackt, featuring both new material and re-recorded tracks. Their subsequent albums included Ich will alles (2009) and Aufstehn - tanzen! (2011), both on Sunny Bastards Records. After switching labels to Artist Station in 2015, they released Noch ne Runde (2015). In 2016, a change in the band's lineup led to the release of Du sollst frei sein in 2019, accompanied by a club tour across Germany.
