This recording is of Prelude Internationale for Organ Op. 5 from Ten Pieces for Organ Op. 1-9 by Steven Monrotus.
Dedicated to the memory of French organist/composer Louis Vierne (1870-1937)
this work for 2 hands is written in the same 6-part form that Vierne taught his students for improvising on a single free theme. Its devices and vocabulary are very reminiscent of Vierne.
The audio clip is the computer-generated piano version.

Form" sub-page, for additional details].
