On Thursday 19th June 2025, Thomas was officially announced as the newest member of APOLLO5, a critically acclaimed vocal ensemble based in London who tour all over the world. The group tour all over the UK, throughout Europe and further afield including the USA and Asia.

APOLLO5 are a five-piece vocal ensemble from the UK based in London. Since the group's formation in 2011, their continuing aim has been to tell stories, stir emotions and inspire audiences through singing. Taking a diverse and dynamic approach to programming, APOLLO5's extensive repertoire spans over half a millennia, and their six studio albums and international performances have garnered them critical acclaim and a close community of followers, both in-person and online.

I am thrilled to be joining Apollo5 as their newest member during their 15th anniversary year! Apollo5 has always performed with such exceptional musicianship and to be a part of such a creative and inspiring group is a real privilege. I can’t wait to begin!

Thomas will join APOLLO5 for the first time at Milton Abbey as part of the VOCES8 International Festival 2025. Tickets are available here. The website says:

'Join the critically acclaimed vocal ensemble APOLLO5 at Milton Abbey, Dorset, as part of the VOCES8 International Summer Festival, for a captivating evening of music inspired by their celebrated 'Anam' album.

Blending rich Celtic themes with new arrangements of folk songs, pagan texts, and poetry by Robert Burns, the programme weaves together tradition and innovation. Expect soulful melodies, evocative harmonies, and even the haunting sound of traditional instruments like the Uilleann pipes.

This concert also marks an exciting new chapter for APOLLO5 as they welcome their new tenor.'
