Kaaos formed in March 1980 in Tampere, Finland. In the beginning of 1981 the first real line-up started to play noisy hardcore with UK & US influences. Kaaos' first 8 song EP came out as a split release with a band called Cadgers (later named Riistetyt), followed by some chaotic gigs and a couple of songs for various compilations. While guitarist (and later vocalist) Jakke being the only original member, the line-up changed frequently. As the band had very loyal fans all over the world they released their famous Totaalinen Kaaos EP on Propaganda Records instead of breaking up. The Ep became one of the best selling finnish records ever. The album Ristiinnaulittu Kaaos appeared early 1984 on Barabbas Records. During the bands first European tour German Weird System label put out a Kaaos/Terveet Kädet split LP called So Much Fun. In 1985 Kaaos gigged all over Scandinavia and the rest of Europe, recorded another Ep (which came out in 1993) and did their final show in December ´85.
