Henry Montgomery – Bass
Henry is a bass from the north of Lincolnshire, and started singing through local musical theatre productions and in the National Youth Choirs of Great Britain.
His love of choral singing led him to read music at the University of Cambridge, where he sang daily with the Choir of St. John’s College, and in its close-harmony group, The Gents of St John’s. Whilst at university, he balanced choral singing with solo performing, and took part in many university opera society productions and recitals. Henry had the privilege of learning with Joseph Middleton on the Sir Arthur Bliss Lieder Scheme, and performing as Christus alongside Nick Mulroy in performances of the St. John Passion last year.
After graduating, he took up a place as VOCES8’s 2024-25 bass scholar, and a lay clerkship in the prestigious Choir of King’s College, Cambridge, where he sang for millions of people on TV and radio over the Christmas period.
Outside of singing, Henry is a keen footballer and Grimsby Town fan, and has recently become somewhat obsessed with barbershop quartet singing. He is absolutely delighted to join Tenebrae as their new Bass Associate Artist this year!
