SonoConsult Håkan Sjögren Ab

SonoConsult started as a partnership (Sjögren & Ingelstam AB) between Rolf Ingelstam and Håkan Sjögren in 1969 (at that time both worked at the Royal Institute of Technology in Stockholm in the fields of Audiology and acoustics) and made all of the recordings for Proprius records during 1969-1973. During the 1970:s Håkan was responsible for the electro-acoustic equipment in the concert hall of Stockholm. Several recordings of the symphony orchestra were made during this time together with Ulf Rosenberg. In the late 1970:s and 1980:s recordings were made for other labels among others the Christmas and Lucia song records by the Nacka choirs directed by Carl-Bertil Agnestig. SonoConsult was not active during 1982 -1995. After 1995 until present the recording activites were restarted. In 2009, a unique collaboration between the "Sveriges Körförbund" and Naxos started to document the Swedish choir life in all its breadth and diversity. SonoConsult is the project manager and has recorded most of the releases so far.
