Geraint Bowen was born in London and received his early musical education as a chorister at Hampstead Parish Church under Martindale Sidwell. He was organ scholar at Jesus College, Cambridge, and was later assistant organist at St Patrick’s Cathedral, Dublin and Hereford Cathedral. His organ teachers included Christopher Herrick, John Scott and Sir Stephen Cleobury.

From 1995 to 2001 he was organist and master of the choristers at St Davids Cathedral, Pembrokeshire. In 2001 he took up the posts of organist and director of music at Hereford Cathedral, conductor of Hereford Choral Society and artistic director of the Hereford Three Choirs Festival. Work with the cathedral choir has included CDs of works by Byrd and Howells, a tour of South Africa and six tours of the USA, performances of Bach’s Passions and Christmas Oratorio, and two liturgical cycles of Haydn’s last six masses. Broadcasts have included Choral Evensong for Ash Wednesday on Radio 3, including Allegri’s Miserere, and the cathedral’s Easter Day Eucharist on BBC One.

At the Three Choirs he has commissioned works by Sir Richard Rodney Bennett, Kerensa Briggs, Bob Chilcott, Sir James MacMillan, John McCabe, Anthony Powers and Dobrinka Tabakova, and has worked with the Bournemouth Symphony Orchestra, the City of Birmingham Symphony Orchestra, Florilegium, the Philharmonia Orchestra, and the Royal Philharmonic Orchestra. A highlight of the 300th anniversary festival at Hereford in 2015 was a performance of Bach’s St Matthew Passion with the Three Cathedral Choirs and the Orchestra of the Age of Enlightenment, which was later broadcast on Radio 3.

In 2018 the cathedral choir travelled to Rome, where it sang a concert in the Sistine Chapel with the Cappella Sistina, and at a Papal Mass in St Peter’s Square. In 2019 the choir took part in the 75th anniversary commemorations of D-Day in Normandy.
