Singers and conductors from various choirs (at least three nationalities) practised three songs under the meticulous directions of the genial composer in three sessions beginning at ten in the morning in the little church presided by the Benidictine nuns.
It was both a challenge and a pleasure to work with dedicated and focussed people in such and intensive way. 
Very expressive and communicative
The whole group
In the evening we sang our three rehearsed songs in the cathedral, after which we were presented with attendance diplomas. The icing on the cake was the performance of Aqua Lauda, conducted by Javier Busto. They were so goood that some experienced choir singers felt like giving up!
Aqua Lauda, conducted by Javier Busto, singing Ave Maria, the conductor's own work and God be in my Head by David Basden.
I've just checked "genial" in the dictionary- friendly and cheerful, nothing to do with "genius", but you can use both genial and genius for Javier Busto.
