Schwein's activity began in early 2009, but their official start date is unknown. They began playing as a session band under the name Uninstall. The lineup consists of vocalist hina, guitarist yam (ex-SHUFT), bassist yairi (ex-Verfe~gorl) and drummer takeru.
By June 2009, the band ended their session activities and chose to make the band official, calling it Schwein which is german for pig. Schwein played their first official concert on July 3rd at Nagoya Holiday, among bands such as THE EIGHT, DEPAIN and emmurée. On August 5th, the band released their first single dokusai no buta, which was followed by a short tour at the end of the month.
While the band is still very new, fans are eager to see what Schwein will produce next.
