An alumnus of the Royal Academy of Music - where he studied under Michael Dussek and James Baillieu - Jack has held prestigious young artist positions at the Georg Solti Accademia in Venice and the Oxford International Song Festival alongside soprano Clara Orif. His collaborative skill is marked by pianist prizes at both the AESS English Song Competition and the John Kerr Award.

As a recitalist, Jack frequently appears at landmark venues such as Wigmore Hall and St Martin-in-the-Fields. Much of this work is centered on Duo Melus, his partnership with flautist Katie Taunton; the pair is currently supported by the City Music Foundation to champion Welsh composers and commission contemporary repertoire. His operatic portfolio includes work for Glyndebourne Festival Opera and Lyric Opera Ireland, as well as continuo appearances with the Orchestra of the Age of Enlightenment. Looking ahead, Jack will join Glyndebourne for The Marriage of Figaro and collaborate with The Sixteen for a new chamber opera by Will Todd.

Jack is also an established composer whose works have been commissioned by Oxford Song and broadcast on BBC Radio. His award-winning output includes the song Bright Sunlight (2nd prize, AESS) and the choral motet May the Mind of Christ My Saviour, published by the Church Music Society via Oxford University Press.
