They had their first concert in 1979 when most members were only 13. The gig was such a success that they were immediately banned by the regime and withdrew to private underground performances ever since.

After the 1989 revolution their popularity and cult grew fast and they toured around many European countries and festivals.

"There has always been something punk in our music. It gives the punks somethin different than ordinary punk bands do, but I feel we have a lot in common." Filip Topol, 1999.

The group split in 2011 because of personal and health reasons.

In December 2012 the band resumed activity.
