Vox Cordis was formed in 1998 by a group of friends who wanted to continue singing after leaving university. It has since gone from strength to strength under its two conductors, Matthew Altham and Charlie Grace, taking on a wide-ranging repertoire from the great polyphonists of the sixteenth century, through music hall (under its occasional name, the 'Velvet Chords'), to modern classics such as the works of John Tavener.

The choir gives regular concerts in churches throughout London as well as performing elsewhere across the United Kingdom. Highlights of its engagements to date include a concert for the bicentenary of Trafalgar in aid of SSAFA at Bath Abbey with the Bath Philharmonia, Bach's Mass in B minor with the Linden Baroque Orchestra, Bach's St John's Passion in Kensington with the Scottish tenor, Mark Wilde, as Evangelist, and Britten's St Nicolas at Holy Trinity, Prince Consort Road, in aid of the National Playing Fields Association.

The choir has also given Summer Serenade concerts at St Luke's, Chelsea, for Macmillan Cancer Relief, performing with Simon Bates and Sue MacGregor. As the Velvet Chords the choir has performed in fund-raising events at the celebrated Wilton's Music Hall in the East End of London.

In addition to these concerts in support of charities, the choir has also sung at weddings, sung services at Norwich Cathedral, staged a programme of unaccompanied English music at the annual 'Music at Beaulieu' festival in Hampshire, and given an outdoor lakeside concert for the Golden Jubilee at St Paul's, Walden Bury.  Vox Cordis is particularly in demand at Christmas, with carol concerts at the Victoria and Albert Museum, at St Luke's Chelsea for the Charlie Waller Memorial Trust, at the Holy Redeemer, Cheyne Row for the Foreign Aid Service of the Order of Malta, and at 10 Downing Street for the Prime Minister's Christmas party.

The choir's patron is the English baritone, Simon Keenlyside CBE.
