It's a real pleasure to hear Radio 3 devoting time to an organ recital - and with David Goode playing Bach on the Metzler at Trinity there's real inspiration.
The history of the instrument is on

I saw reference to its "idiosyncratic" tuning and this was music to my ears. Bach really comes alive on the Metzler and http://www.cambridgeorganacademy.org/bachand.htm relates that it's tuned to Werkmeister. If only more instruments were tuned to systems with perfect fifths . . .
Best wishes

A really good recital and one of he instruments I would like to hear live.
