Rattus is a seminal Finnish hardcore punk band formed in 1978 in Vilppula. Known for their aggressive sound and politically charged lyrics, they quickly became a cornerstone of the Scandinavian punk scene. Their debut album, *WC Räjähtää* (1982), is considered a classic in the genre. After disbanding in 1988, Rattus reunited in 2001 and continues to influence the punk community with their relentless energy and uncompromising message.
