This album presents transcriptions of Mozart’s *Eine kleine Nachtmusik*, Symphony No. 40 in G minor, and Quartet in C, performed by Hans van Nieuwkoop and Jacques van Oortmerssen on the historic Bätz organ in the Grote Kerk, Harderwijk, Netherlands. This unique interpretation brings a fresh perspective to Mozart’s compositions, as the organ transcriptions emphasize the pieces' melodic and harmonic intricacies, blending church tradition with classical charm. The program highlights the role of organ transcriptions in the late 18th and early 19th centuries, when organists often adapted symphonic and chamber works to showcase the organ's versatility.
