Speranza was founded in Moscow in 2007. It developed from the work of the Christian charity Crescendo and was designed as a flexible chamber group performing in a wide variety of venues. It has since relocated to the UK and has performed a wide range of concerts featuring flute, cello, piano and other instruments.

Kath Sugden BMus (hons), PGCE, LTCL studied music at Cardiff University and flute with Roger Armstrong. Having taught for a number of years, she moved to Russia and set up the Christian organisation Crescendo, working mostly with conservatoire students across Russia. There she studied with Valentina Daktyrova at the Gnesin Academy. She has performed in venues across Europe and is particularly interested in music from the 20th Century.

Charles Sugden studied history at Cambridge though he was formerly a music scholar at Radley College. Having started as a flautist, he has since developed as a cellist, which instrument he is normally to be seen playing at Speranza concerts. As well as being a performing musician, Charles is also the chaplain of the Bournemouth Symphony Orchestra.

Chris Coote LTCL started playing the piano at the age of four, and performing from eleven, mainly to captive audiences in old people's homes. He has attended master classes for many years at Morley College under Martino Tirimo and Gwenneth Pryor, and was taught by Jean Anderson and Fiona Cameron, both retired professors from the Royal Academy of Music. Since retiring fully from professional life as an actuary in December 2013, a replacement career has opened up, and he now performs regularly as a soloist and accompanist.
