Siegfried Reda is another of those modern Germanic composers that is rarely played - and, I get it - it's sometimes rather thorny and dissonant music...
We hear the Advent Chorale "Nun komm, der Heiden Heiland" on the newly-rvised 1983 Schantz, a nice vehicle for this Neo-baroque music.
One little neat feature of this ABA form piece - in both "A" sections, the theme is a (short) 3-part canon!
