Ralph Blakely on Willem Tanke's Super Audio CD Meditations for a lent in American Record Guide:

"I reviewed two fantasies by Willem Tanke in the March/April issue this year. I found Tanke one of the most fascinating composers I had encountered. Now, this work confirms and augments  that judgement...However, ingenuity does not make art; it is the remarkable beauty of this work that does.  This recording will be a the top of my critic’s-choice list for the year. I believe it may be the most important recording I’ve reviewed for ARG. Tanke wrote that he intended to explore the direction music is headed in the 21st Century. If that be so, I am excited about where it is going."

Besides his own music, Willem Tanke's interpretation of organ works by J.S. Bach, Max Reger and Olivier Messiaen on excellent historical instruments is of the highest order: 

Willem Tanke documents his expertise on a special website, called Playing Keyboard Instruments in the 21st Century

His recordings are almost always made in one track, without edits, to preserve the natural flow of performance and provide authenticity.
