Athletic Sound was established in 1983 by Kai Andersen.
The studio is located in Halden, a small quiet city 120 km outside Oslo, and only 5 km from the Swedish border.
The studio is situated in an 18th century building, which in the early days was a gym.
The building has seen a steady stream of internal changes and improvements over the years, and offers comfortable surroundings for the studio.
Kai Andersen, the owner of the studio has produced and/or engineered hundreds of independent and major acts. A lot of the albums have reached gold and platinum, as well as receiving Norwegian "grammys".
