Barnaby also founded and sings with the award-winning a cappella ensemble Voces8. With the group, Barnaby has toured extensively in eleven countries in 2007/08. Future concert performances will take the group to Spain, Italy, France, Belgium, Germany, Kenya and the USA in 2009. Performance venues include St John Smith's Square, the Wigmore Hall, The Royal Festival Hall, The Royal Opera House, King’s Place and the Purcell Rooms.
Barnaby's conducting duties include principal positions with Voces Cantabiles, the Senesino Players and Bracknell Choral Society. Recent CD releases include the music of Robert Parsons for Naxos which was received to great critical acclaim.
As a soloist, Barnaby has appeared with the Orchestra of Opera North (JS Bach’s Magnificat and Vivaldi’s Goria), in a six-concert tour of Handel’s Messiah with Paulo Ali and the Jubilate Orchestra in Italy; Handel’s Dixit Dominus and Bernstein’s Chichester Psalms with Rupert Gough; a semi-staged production of Handel’s oratorio Saul with the Bray Ensemble; and Bach’s St Matthew Passion and St John Passion. In his operatic debut, Barnaby performed the role of Bertarido in Handel’s opera Rodelinda. Also a recitalist, he has performed in venues including Christ Church Cathedral, Oxford, and the Swiss Church, Covent Garden. Recent engagements include a solo recital for the Musician’s Benevolent Fund at the Foundling Museum in June 2008 with a programme exploring the solo arias of Handel, Purcell and Dowland.
In the studio, Barnaby’s latest recording projects include a disc of music by Bach and Handel which explores the links between the lives of the composers and the fortunes of the archetypal Baroque Hero. This new disc, due for release in 2009, features the Senesino Players, Voces Cantabiles, Thomas Gould as violin soloist and Barnaby as Director and countertenor soloist.
