Originally formed in 1995 as Sperrzone in Hamburg, Germany, they started off playing rough hardcore. At some point in the late '90s they renamed the band Instinct of Survival and changed their style to grindcore. Around the mid-'00s they changed their style again, this time to the stenchcore sound they are known for today. Band's MySpace page: http://www.myspace.com/stenchcore Read more on Last.fm
