Second upload (I forgot to record one of the variations; now it's complete!)...
A partita on the Advent song "Kom tot ons, scheur de heem'len, Heer" by Dutch organist and composer Folkert Grondsma (1944-2000), written in a style that was highly influenced by Vierne, Langlais and Messiaen.
In English this song is called "O Savior, rend the heavens wide", so I guess that will help you to understand the meaning of the rather dissonant chords in the first (and the last) part.
