Here's a review from The Guardian on the Kings Singers Proms concert
of Aug 5th. Other a cappella artists at the Proms are I Fagiolini and
Theater of Voices.

"The late-night Prom featured the King's Singers, whose versatility
and sheer musicianship have kept them at the top of the range of a
cappella consorts for an amazing 40 years. The current lineup's
programme contrasted French Renaissance chansons, including virtuoso
accounts of Janequin's La Guerre and Passereau's Il Est Bel et Bon,
with some cleverly contrived French folksong arrangements by Poulenc.
John McCabe's Scenes in America Deserta, which sets texts by Reyner
Banham evoking the colourful landscapes of the south-western US,
provided a substantial challenge. Its vivid word setting and inventive
vocal writing proved superbly atmospheric, and the group's centred
performance was immaculate.

Their final sets, selections from the Victorian part-song repertoire
and English folksong arrangements by Gordon Langford and two of the
group's past or present members, sounded a little too eager to please,
though flawlessly realised. Arthur Sullivan's close-harmony setting
The Long Day Closes proved an inspired encore."
