S.i.K. is a German punk rock band founded in June 1991 in Winnenden, Baden-Württemberg, by Andi, Fraggle, Jürgen, and Manu. To release their music independently, the group established the label Nix-Gut Records in 1994. The band's early releases include the 1993 demo tape Kanonenpower, followed by their debut album Vergiß es! (1995) and Keine Frage (1998), both issued on their own label. Subsequent albums include Zeiten ändern sich (2002), Hältst du still?! (2009), and Schnauze voll (2013), which are known for addressing political themes such as war, xenophobia, and legal injustices. The band's music label subsequently expanded into one of the largest punk mail-order operations in Germany.
