Liehsja began the folk harp at the age of nine in Aberdeen, Scotland. On moving to Sussex she gained a scholarship to study the pedal harp with Helen Arnold.

She toured with Brighton Youth Orchestra to Hong Kong in 1999 and to Italy with the East Sussex Youth Orchestra the following year. In 2003 Liehsja made her debut as a soloist with the Keele Philharmonic Orchestra touring to Paris and across Brittany performing Debussy's 'Danses'.

Graduating with Firsts in Performance from Keele Liehsja was invited to join Birmingham Symphonic Winds to attend the prestigious Midwest Clinic World Conference in Chicago, December 2003.

Liehsja has been involved in writing, arranging and improvising music for the Pericles Theatre Company, performing the Children of Lir (2000) and Bench (2005).

As a freelance harpist Liehsja is in demand for solo work, orchestral playing, weddings, parties and functions and has recently performed at a number of venues including Kensington Palace, the London Carlton Towers Hotel and The Royal Military Academy Sandhurst. As a member of the folk band 'Andrew Norman and the Blaxland Sisters' she was invited to headline at the Chiddinglye Folk Festival in October 2004. She supported Niamh Parsons in September 2005, and will be supporting Last Night's Fun at Hailsham Pavilion with her band Wasps in the Woodshed.

In July 2005 Liehsja ran a workshop on the seventeenth-century Irish harper Turlough O'Carolan, as part of the Cambridge Music Conference on the theme of the heart (other contributors: Sir John Tavener, Nigel Osborne). Brian Keenan, author of 'An Evil Cradling' and 'Turlough', joined the group for one afternoon, discussing his connection to O'Carolan.

During April and May 2006 Liehsja and Francois Pernel, a harpist from Paris traveled the UK with their Contemporary Celtic Harp Tour. They performed a series of 21 concerts of O'Carolan arrangements and Liehsja's compositions to a range of audiences including adults and children with special needs.

In September 2006 she lectured in Belfast on O'Carolan's music and the work of Brian Keenan at the International Lyre Conference.

Liehsja performed at Webmley arena in September 2006 for an event dedicated to the United Nations national day of peace. Shortly after, her compositions were featured in two theatre shows called Bench and Woman at Chequer Mead Theatre in East Grinstead.
