Athletics Sounds owner and main resident technician and producer, Kai Andersen, does not even have an overview of how many recordings have been made in the Halden studio during its first 25 years - but there are not a few. Several of his most famous and successful clients gathered to mark the anniversary in Brygga Kultursal in Halden on Tuesday 28 April 2009, and that poster reads as a selection of Norwegian rock's nobility calendar. Rarely do you see a similar list of Norwegian artists on the same stage, the same night.
In addition to the concert itself, there are also large amounts of unique bonus material. Most were filmed or shown the same day, either in live-streamed broadcast backstage or from the stage.
