The second piece by Karges from manuscript Am. B340 is a beautiful praeludium. It flows elegantly in long arching lines. There's not much in terms of thematic of motivic development, yet the music manages to form an coherent whole.
The recording was done with the Hauptwerk software and the sample set of the Mascioni organ of the parish church in Azzio, made by Piotr Gabrowsky.
