The first CzechTek was held in 1994 at Hostomice, it was organized by the Spiral Tribe sound system and a group of artists called the Mutoid Waste Company.

The organisers claimed to have permission from the landowner to set up the event, but shortly after the festival began, around 1,000 riot police arrived, using heavy equipment including tear gas, water cannons and the military BVP vehicle.

The Prime Minister, Jiří Paroubek, defended the action, declaring that the tekno fans were "not dancing children but dangerous people".

Close cooperation with the state administration caused some resentment among the freetekno community, but the festival went ahead without any repeat of the previous year's violence.
