It is promoted by one of Austria's national radio stations, FM4, and is generally associated with the alternative part of mainstream music.
One of the major Austrian concert organizers–promoters and business rivals of Musicnet, Wiesen, who are also in charge of famous Austrian festivals like the Jazz Fest, Forestglade and Two Days A Week, decided to have Metallica perform in the stadium of Salzburg, only about 20 km away from the Salzburgring, on the second day of the Frequency festival.
Logistic and sanitary problems were the result and it was seen by many critics as a miracle that there were almost no serious injuries and not even a single death.
The festival was overshadowed by a huge storm with winds up to 140 km/h during the first night and constant, intense rain showers during the second day.
31 people were injured, although none seriously, but a panic could be averted, mainly thanks to the coincidence that the Red Cross tent was very close to the bridge.
The organisers very quickly secured and illuminated the area and arranged pathways for ambulances to come in and pick up the injured.
They had hired a construction company that built the fundament of materials not suitable for outdoor use, unlike what had been agreed on.
Pioneers of the Federal Armed Forces of Austria (the Bundesheer) constructed a replacement bridge out of aluminium and steel that very night, so that it could be used on the remaining, third day.
