Andante Religioso. Op 28

Felix Dreyschock
(27 December 1860 in Leipzig – 1 August 1906 in Berlin) was a German pianist, nephew of Alexander Dreyschock.
He was a pupil of Friedrich Kiel, Wilhelm Taubert and Heinrich Ehrlich in Berlin, where he in 1883 began to give concerts. In Stockholm he performed successfully in 1886 and 1889, both as a virtuoso and composer.
He wrote major and minor works for piano, violin, vocals, orchestra, etc.

This is a rewarding piece of music to play in the organ arrangement although it has it's challenges I found.
