The recordings made during the colloquium at Duquesne are online
here, courtesy of Carl Dierschow. Scroll down the page a bit for the individual masses. If you're curious about the polyphonic choir I was in, listen to Elisabeth Zachariae on Thursday, Reminiscere miserationum tuarum on Friday and the Schubert on Sunday.
I hope you can't hear me but I was singing more or less in all the Lauds and Complines as were those of us who attended those at 7 am and 9:30 or so pm.
Thanks, Carl!
