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.
