I need to correct something that I wrote here. I realized that I somehow managed to mix up two different churches and organs in Dresden. Contrary to what I wrote, the organ in the Silbermann SoundWalk video is not the Kern organ. The church in the Silbermann SoundWalk video is the Hofkirche in Dresden. The Kern organ (2005) is in a different church in Dresden, the Frauenkirche, which previously had a Silbermann organ.
Some contemporary "Music for Strings" by Terje Bjorklund.
Both music and composer are new to me.
Quite laidback, tonal.
An interesting and pleasant listen.
