Imogen Heap & the Holst Singers

It isn't often you hear six members of the Estonian Television Girls Choir join forces with the Holst Singers and Imogen Heap to perform a live a cappella soundtrack to a 1920s French surrealist film about a libidinous priest. But I am delighted to have seized the opportunity last night, when this bizarre setup hit the Camden Roundhouse as part of this year's genre-baiting Reverb festival.
