Old instruments have found young champions this week in two very different concerts and contexts. In the Wigmore Hall, Mahan Esfahani continued his persuasive rehabilitation of the harpsichord, showcasing not only the expressive range of the instrument itself but – more unusually – its repertoire, in music from Byrd to Ligeti. Meanwhile out in Richmond young singer-songwriter Joseph Reuben took a string quartet on a stylistic journey, blending classical textures and processes with an indie-pop sensibility to create a thoughtful fusion.

Bach for breakfast, lunch and supper. That in essence was what yesterday's Bach Marathon was about. You can do that with Bach - have him flowing from the taps. Nothing new in this for those of us who experienced the Bach Christmas a few years back on Radio Three, when every note was piped over the airwaves for breakfast, lunch and supper for 10 days solid. Nothing very marathon-like about any of it, though, either. The day’s performances couldn’t have been further from a challenge to sit through or listen to. 

It’s only fitting that Sir John Eliot Gardiner should be celebrating his 70^th birthday with a concert in the Royal Albert Hall. That it should be a nine-hour marathon of a concert is not only fitting, but entirely predictable for a musician who has always kept one eye on the next and biggest challenge.

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.
