A Leipzig church is surely the place we’d most like to be for Bach on Good Friday. Never mind: the Barbican Hall is kinder to the best period instrument ensembles than it is to big symphony orchestras. Better still, having sat stunned and weepy for a good few minutes at the end of this performance, I’m happy to evangelise and proclaim that no better team could be assembled anywhere for the original 1724 version of this world-changing musical Passion.

Bach: Harpsichord Concertos Retrospect Ensemble/Matthew Halls (harpsichord and director) (Linn)

Kings Place’s Bach Unwrapped season invites audiences to come at the composer from new and unexpected angles. Bach gets arranged, adapted and re-orchestrated, and his legacy is showcased in works from three centuries. Occasionally however he also gets played straight – and it doesn’t get much straighter or more authentic than the Academy of Ancient Music and the Choir of King’s College Cambridge performing the St Matthew Passion.

Faced with yet another world premiere from his friends in the Borodin Quartet, Shostakovich severely asked them whether they’d yet played all of Haydn’s quartets (they hadn’t). As a listener, I feel the same about Bach’s cantatas. Whether or not a lifetime will be enough to catch each of these varied and ever surprising little miracles in the flesh, Kings Place’s Bach Unwrapped series includes a chance to hear nearly 30 of the 200 from seven different ensembles in less than a year. Unfortunately it looks as if I drew the short straw at the end of the first four concerts.

Bach: The Well-Tempered Clavier András Schiff (ECM)

When you hear Christian Tetzlaff play you hear Brahms, or Beethoven or, in this case, Bach. What you don’t hear a lot of is Tetzlaff himself. I mean that in the best possible way – so willing is the violinist to submerge himself, to set aside ego and agenda. It’s an approach that is at its purest in Bach’s solo violin music, and as he presented the sonatas and partitas to a full Wigmore Hall last night the generosity of this extraordinary musician allowed his audience to set ourselves aside for a moment too as we listened.

I'd love to see the stats on the last time a Prom was this packed for an afternoon organ recital. Were it not for the fact that organist Cameron Carpenter was sporting spandex trousers encrusted in silver glitter, a wife beater and Mohawk, you could have been mistaken for thinking we were back in the organ glory days of the early 19th century. Even the programme harked backward, offering as it did big, bloated Romantic transcriptions, arrangements and improvisations (pretty much everything in fact except the urtext).

What better work for Harry Bicket and The English Concert to perform at the Proms than Bach's joyous Mass in B Minor. Joyous firstly because of the music itself, with its vast stylistic and emotional range. Joyous secondly because, despite the intense scholarship to which Bach and his music have been subjected over the years, its genesis remains unusually shrouded in mystery for such a major work.
