Born in Halifax in 1977, Tom Williams began singing at an early age. A former chorister of Ripon Cathedral and a music scholar at Uppingham School, he went up to Cambridge University in 1997 where he read music. As Senior Choral Scholar in the world-famous choir of King's College, he was musical director of Collegium Regale, an a cappella vocal ensemble formed by the choral scholars. With them and the main choir, he toured extensively in Europe, the USA, Australia and the Far East.

As a countertenor soloist Tom has performed Rachmaninov's Vespers in Ghent Cathedral and in the presence of Mikhail Gorbachev, Mozart's Missa Brevis in F in the Lincoln Center New York, Bach's Magnificat in King's College Cambridge, Handel's Israel in Egypt in the Dortmund Neues Konzerthaus, Finnessy's Anima Christi at the Huddersfield Contemporary Music Festival, Bach's St John Passion in Jesus College Cambridge, and Tippett's Lullaby in the Aldeburgh Festival. Other solo performances have included Bach's St Matthew Passion, Handel's Messiah, Bach's Christmas Oratorio, Mozart's Requiem and Haydn's Stabat Mater.

Tom now lives in Leicester and works as a vocal tutor, conductor and freelance singer. He is a member of the choir of the Temple Church, Polyphony, Oxford Camerata and the EXAUDI Vocal Ensemble. With the latter he recently appeared as a finalist in the 2006 Royal Overseas League Annual Music Competition and was nominated for an RPS Award in 2006 and 2007. The group performs regularly for the BBC and other European broadcasters.

Tom has recently formed a new six-man a cappella vocal ensemble, SIX8 and became conductor of the Leicestershire Chorale in January 2005. He has received much critical aclaim so far for his direction of Chorale, winning the Leicester Mercury's 'The Week Awards' category for Best Classical Performance of 2005. In February 2007, he made his conducting debut at Leicester's De Monfort Hall, directing a chorus of 300 and the Leicestershire Camerata in John Rutter's Feel the Spirit. He will conduct a similar event in 2008, involving the Leicestershire Schools Symphony Orchestra. In April 2006, he directed the Northampton Bach Choir and the singer-presenter Aled Jones in the Derngate Theatre in Northampton.
