Vox Duo is an independent musical collaboration founded in 2018 between Scottish soprano Karla Grant and British-Brazilian mezzo soprano Julia Solomon.

Praised for their blend of voices, Vox Duo put their own stamp on duets, old and new. Vox Duo are versatile artists who enjoy exploring a range of musical genres and performance settings. They work in close collaboration with pianists to present recitals of art song, opera and new works by up and coming composers. They have performed across the UK in their own Vox Duo concert series, at the Glasgow Art Club, Kodàly Erasmus+ Event in The National Piping Centre, The Wellington Arts Festival and The Linlithgow Arts Guild in St Michael’s Parish Church.

Vox Duo were proud to join Live Music Now Scotland in 2020. Together with Live Music Now they have performed for the Saughtonhall Women’s Union and Live Music Now Scotland’s ‘At Home’ series. Most recently, Vox Duo recorded a Christmas concert as part of Live Music Now Scotland for the National Galleries of Scotland in the Great Hall in the Scottish National Portrait Gallery. 

In 2021 Vox Duo began an exciting new venture collaborating with the Earthtones Trio, recording new compositions by composer Euan Stevenson. In December 2021, Vox Duo released a recording with Earthtones Trio, which has been broadcast on BBC Radio 4 Woman’s Hour. Vox Duo now work with iOcco Music as iOcco Music Artists.

Both completed their postgraduate studies at the Royal Conservatoire of Scotland in June 2022, having both gained a First-Class Honours Bachelor of Music in Vocal Performance in 2020 also at the RCS under the tutelage of Wilma MacDougall.
