Eleni Violaris was born in London to a family of professional musicians. Her father is of Greek heritage and her mother, Welsh. Eleni, who sings and plays the piano, flute and guitar, has been making music & taking part in professional recordings since she was five years old. As a youngster, Eleni recorded children’s solo & chorus parts on a double CD recording of a contemporary music drama entitled, ‘El Cid’, written & composed by her father (Andonis Violaris) in discussion with Placido Domingo. Andonis also wrote, composed & produced songs for the "60-million” album-selling artist, Demis Roussos.

At 12 years of age, Eleni, together with her younger brother Adam Violaris, performed & sang to a special delegation from the United Nations Environment Programme (UNEP) in Geneva. This resulted in a commission to record a  single & music video entitled, ‘'Children for the World - Call You Now’, to help support UNEP’s outreach programme during the ‘Year of the Mountains’ in 2002. Eleni’s stand-out solo vocal performance on the single attracted the attention of record label executives at Sony Music & Polydor. Eleni is also an actress & classical ballet dancer, who considered a dancing career after being talent scouted for the Royal Academy of Dance but decided on a professional music career instead.

Eleni went straight from college to singing, composing & writing songs (words & music) for major BBC arts programmes, including the 12-part BBC Two series, ‘Francesco’s Mediterranean Voyage’ & the landmark BBC One David Dimbleby series ‘Seven Ages of Britain’, in which she worked alongside her brother, Adam Violaris, also a composer on the series, as well as her father, who was the executive music producer of the series. Eleni performed all the vocal cues on the ‘Seven Ages of Britain’ series, including co-writing & performing the end title song in Anglo-Saxon; a concept she developed for the series. Eleni also co-wrote & performed a number of songs & cues in Latin and Hindi. Eleni also recorded two Italian arias, written & composed by Adam Violaris. It was the Italian aria for the scene of David Dimbleby in Renaissance Florence that excited & prompted Sony Classical & Warner Classics & Jazz to offer to release a soundtrack CD of the series. This encouraged Eleni & Adam to write the concept album, ‘Rainstriker’, which Warner's  offered to release back-to-back with the ‘Seven Ages of Britain’ soundtrack CD.

In 2012, Eleni toured with Andrea Bocelli in the UK as a backing singer as part of the acclaimed Crouch End Festival Chorus, which included performances at the 02 Arena & the Birmingham NEC, as well as the televised Classic Brit Awards at the Royal Albert Hall. Eleni has also recorded backing vocals on albums by Katherine Jenkins & Lesley Garrett, again with the CEFC.
