A three part chorale prelude on 'Auf meinen lieben Gott' by Moritz Brosig (1815-1887), played on the Beta 2 version of the upcoming sample set by ForestPipes 'Hildesheim, St Godehard'.

At first you'll hear a forte introduction on the first part of the melody, indicated with 'Volles Werk, ohne Mixturen, Quinte 2 2/3 und Superoktave 2'. A full and rather dark sound.
The second part is a lovely Adagio, played on soft foundation stops (Man.II and III), with a solo on the beautiful Flutes of Man.I.
The conclusion is a massive chorale, played on (again) almost full organ.
Enjoy!

P.S.: the Youtube also plays two other pieces by Brosig; I hope you'll enjoy them too :-)
