Such is the profile and schedule of The Sixteen that I was surprised to find that their short tour of the Monteverdi Vespers was the first time they had toured with orchestra and choir together. Of their eight venues (six cathedrals, and two concert halls), I saw them in Guildford Cathedral (on 30 Jan), a pared-down Gothic building designed in the 1930s and finally opened in 1961. The acoustics are good, at least from my seat close to the performers, who were positioned in what would have been termed ‘the crossing’ (in front of the choir and chancel) if there had been proper transepts. Very professional looking TV cameras broadcast to monitors to the sell-out audience down the long nave. The sequence of movements was what has become the traditional one, as were several other aspects of the performance including, arguably, taking the sequialtera passages too fast. The (more substantial) Magnificat was sung at higher pitch. With 20 singers and 24 instrumentalists, this was an aurally powerful performance, although the tiny box organ was only occasionally audible. The use of such organs is common in the UK although I urge you to try and hear the Vespers (and any Bach cantatas, for that matter) performed with a church organ (for example, see my review of the Cantar Lontano recording in the October 2014 Early Music Review). The rest of the continuo group was cello, violone, chitarrone, harp and dulcian, with string/recorders and cornett/sackbuts divided left and right. The vocal soloists, all stepping forward from the choir, were sopranos Grace Davidson and Charlotte Mobbs, tenors Mark Dobell and Jeremy Budd and basses Ben Davies and Eamonn Dougan – all most impressive. Relatively limited use was made of the available space, the main exception being the tenor/theorbo duet Nigra Sum which was performed from halfway down the central aisle, and Jeremy Budd singing Audi coelum from the pulpit. The echo passages were sung from somewhere towards the altar. As with their other cathedral venues, the singers in the Sonata sopra Sancta Maria were the local cathedral choristers, in this case Guildford’s very able girls choir.
