The Devon-based vocal ensemble Isca Voices delights audiences by performing a wide range of both sacred and secular repertoire. 

Formed in 2008 as an opportunity for former girl choristers from Exeter Cathedral to keep singing together, the group performs both within Devon and in Europe.

The girl choristers section of Exeter Cathedral Choir celebrated its twenty-fifth anniversary in 2019, having been founded by Stephen Tanner in 1994. In addition to the regular round of service singing as choristers, the choir have appeared in numerous concerts, broadcasts and recordings and have toured in the USA and many countries across Europe. Unlike the girl choristers at many other cathedrals, the Exeter girls leave the choir at the age of thirteen. After four years as cathedral choristers, the girls are very experienced musicians, both vocally and instrumentally. Isca Voices aims to perform not only from the vast wealth of religious choral music from across the centuries, but also music from the folk, jazz and popular music repertoires in close harmony. 

More recently, we have welcomed former Exeter boy choristers into the group, not only to sing lower parts but also as the 'Isca Band' to add an instrumental dimension to our concerts. 

The last three years have seen Isca Voices expand yet further to include adult singers on tours to Paris and Rome with highlights being performances in prestigious venues including La Cathédrale Notre Dame, L'Église de la Madeleine (Paris) and St Peter's Basilica (Rome).

In July 2019, Isca Voices released their debut CD ‘Isca Voices’ which features many of their favourites. The CD is available through the ‘Contact’ page or at our concerts.
