Marc de Leeuw is a Dutch organist and composer. In daily life he works as an independent medical writer. He received his first organ lessons from Kees van Eersel, Gerben Mourik and Arno van Wijk. Currently he is organist of the historic Holtgräve organ (1878) in the Reformed Church of Stolwijk, The Netherlands.
Marc published a bundle with variations on the Genevan Psalm 70 in baroque style. I recorded the first variation in which this phrase is depicted "Daal haastig ter verlossing neer", which means "Descend swiftly to redemption". The regularly recurring descending chromatic bass line illustrates the descent. Although this piece is in baroque style, I think this 'andante meditativo' variation sounds rather well on the model of the Walcker/Eule organ of Annaberg, with its gorgeous flutes and Vox humana.
