Putting the superb Norman & Beard organ in St Martin’s Church through its paces is not just one but two organists at the same time.  The expert and endlessly entertaining duo of Peter Gould and Martin Hall are presenting an assortment of music from across the years stretching back to Thomas Tomkins from the 16th Century to the music of the popular contemporary composer Arvo Pärt.  The concert lasts around and hour and admission is by donation.
