After the deaths of six people at the Time Warp Argentina event in April (16) the Argentine capital's mayor Horacio Rodriguez Larreta announced his staff would no longer allow electronic music events to take place in the city.

The German synthpop pioneers are scheduled to perform at the city's Luna Park Stadium on 23 November (16), but city officials have refused to issue a permit authorising the gig.

"After Time Warp, Judge Lisandro Fastman's court ruling prohibited all electronic music festivals," a city government representative told Argentina's Clarin newspaper. "Because of that, and despite the fact that they presented their paperwork with the required 30 days notice, we cannot authorize the permit."

The official said the ban applied to the group because they use, "synthesizers or samplers as their primary instrument."

Executives at Move Concerts, who have sold around 70 percent of tickets for the gig, are appealing against the decision not to allow Kraftwerk to play.

"They use synthesizers, but what we're proposing is a different format," a representative of the company said. "It's a concert that's open to the public and runs between an hour-and-a-half and two hours. There will also be no alcoholic drinks served."

The band have taken their revolutionary 3D show to cities around the world throughout 2016, with the Buenos Aires gig their penultimate of the year if it goes ahead.
