The Thuringia Schippel-Seeber "Schwalbennest" organ gem in Bedheim is world unique in it's construction.
The Positif unit is located on the wall opposite to the main organ in a distance of about 15 m and is mechanically played by a tracker construction of 20 m length,
which is located in the churchs attic (!), view the small video from Eric Dalest to visit the church
So the organist gets an interesting front and backward sound impression, which only can be realized by with a dummy head mic system and head phones, which was used by OAM.
If you listen to the pieces, close your eyes and imagine the small village church and you'll hear those lovely effects.
