I attended a performance of J.S. Bach's Passion according to St. John (Johannespassion) by the  Hannover Bach Choir and Orchestra last night at the Marktkirche in the central market square of Hannover's old town. I may or may not have listened my way through this work on LP as a youngster, and probably did overhear it on the stereo growing up, but this is probably my first careful listen to the whole piece. (About two hours, no intermission though a brief episode of tuning between the two sections.)  A very rewarding if, obviously, fairly solemn two hours.  Really superb choral singing with the different vocal parts sufficiently distinct and the words very clear (well, especially with the aid of a program given my limited German) but the choir unified.  Remarkably dramatic effect when the choir portrays the crowds present at the high priest's and Pilate's interrogations of Jesus, contrasting with the choir's other main role as expressing Christian sentiments from a point of view that is not necessarily within the narrative aspect of the piece (but might also be taken so, as expressing another aspect of experience of some in the crowd).  The latter is usually in hymn-like chorales, but also often (as in the opening "Herr, unser Herrscher dessen Ruhm") in more complex and extended episodes with more involvement of the orchestra.  The visible wind instruments were baroque in appearance, there was a large lute, and I suspect the string section and most or all of the rest of the orchestra was original style instruments as well.  Tempos were relatively fast, and the resulting sound was excellent, though for some reason the orchestra came across with less clarity than the singers---the relatively reverberant acoustic of the tall, relatively open North German gothic brick hall church maybe having something to do with that. On balance I think the original instruments and the chosen tempos gave a somewhat rough, unprettified, but still accurate and well-played, effect that worked extremely well in the piece, accentuating its seriousness.  Some passages, in which the choir and orchestra engaged in extended contrapuntal reflection upon a dramatic development, or expression of the crowd's intention or reaction, with voices and instruments becoming a swirl of fast-moving harmonies and passing tones, attained an eerie and dramatic effect that reminded me of some twentieth century postserialism, maybe Ligeti or Penderecki.   The soloists were really excellent and did everything well.  Such a performance is definitely not about attention-getting individual vocals but all the soloists did have, in performances that were consistent throughout, some songs that really stood out in expressing key moments in the drama.   Alto Christian Rohrbach has a beautiful clear voice and delivered "Es ist vollbracht!" perfectly; the soprano soloist (either Miriam Meyer or Nadine Dilger; two sopranos are listed in the program) was especially affecting (though never overdoing it) with "Zerfließe, mein Herze" ("Dein Jesus ist tot!"); bass Albrecht Pohl did a great job of handling a variety of vocal tasks in combining the role of Pilate with many additional bass arias.  Johannes Strauß was especially outstanding as the Evangelist---he has an amazingly clear and beautiful tenor voice, deployed with perfect control.

Of course an extended piece like this with religious and dramatic aspects is an occasion for plenty of reflection on musical aspects of the piece but also on these in relation to the human condition.  One of the more interesting aspects of this piece for me was the amount of attention given to the political and social aspect of the story: the interaction with Pilate (I don't fully understand what's going on here yet), the issue about Jesus being called "King of the Jews" but asserting "My kingdom is not of this world", the high priest and the servant, and later the crowd after the exchange with Pilate "Shall I crucify your king?" "We have no King but the Emperor", calling for Jesus' crucifixion.  (There seems to be an emphasis on "the Jews" delivering Jesus to Pilate and calling for his crucifixion in this text.)

A superb, clear, controlled and well-thought-out performance and a perfect way to get better acquainted with this serious, reflective, many-faceted masterwork of Bach's.
