The 'Proms' as they are more popularly known are one of the world's best-known and best-loved series of concerts and best of all, they are available to experience online via the BBC's website.
The Latvian Radio Choir was performing at the Rpyal Albert Hall under conductor Sigvards Klava during an evening dedicated to Russian composer Sergei Rachmaninoff and scored a huge hit with the Proms public both for the quality of the performance and for their stamina to make it through a challenging schedule of three back-to-back recitals.
This year's award for stamina goes to... the Latvian Radio Choir who are performing in three consecutive proms! #PromsFact pic.twitter.com/dl1SHP7l46— BBC Proms Team (@bbcproms) August 13, 2017
"Hailed as ‘the greatest musical achievement of the Russian Orthodox Church’, Rachmaninov’s All-Night Vigil (Vespers) is also one of the loveliest works of any faith – a profoundly moving statement of belief and the last major work the composer completed before he left Russia," the Proms website said.

Following the performance, social media poured praise on the singers.
