It is such a pleasure to discover well crafted, extended organ works and share them with others.
This is the third movement of "Symphonie après Vierne." The chromaticism, so much in evidence in Vierne's later works, is very much on display here. In addition, influences of later French composers are to be seen.
If you missed hearing the Final of this symphony, you will find it in the "Symphonie après Vierne" playlist mentioned below.
