On March 29, 2007 [[Nine Inch Nails]] were confirmed to headline Frequency Festival in Salzburg, Austria [http://www.frequency.at/index.php?id=frequencynews&no_cache=1&tx_music_pi8%5Bnewsid%5D=680&backPid=244 News Archive].
Two months later , German fun-punk-band Die Ärzte, whose fans are known for their obsessive fandom, were announced to play Frequency Festival [http://www.frequency.at/index.php?frequencynews News]. It was soon found out that they were to headline on the very same day as [[Nine Inch Nails]].
The release of the timetable [http://www.frequency.at/index.php?id=frequencylineup2] caused some disconcertment amongst Austrian and German [[Nine Inch Nails]]-fans as [[Nine Inch Nails]] were to play between Beatsteaks and Die Ärzte, two German bands who are very close.
