Jayne was born in Feilding, New Zealand . She showed musical talent from the age of four when she began playing the piano by ear. Jayne has been singing solo since she was 8 years old but didn't start serious training until the age of thirteen when an injury cut short a very promising career as a gymnast. She threw herself into operatic voice training, loving the new languages and the theatre of performing arias, madrigals and close harmony works.

She is very eclectic in her musical tastes, siting Billy Holliday, Pat Benatar and Enya as some of her influences over the years. Elleson would probably describe herself first and foremost as a 'rock chick', having fronted bands long before she was legally entitled to attend her own gigs. The beautiful, ethereal vocal styling for which she has become so well known on albums such as The Blessing Tree and The Chalice and the Changeling are probably a reflection of the more spiritual, emotional side to her character.

Elleson is an award-winning session vocalist having won two Gold Clios in New York for commercials, plus many other accolades including a Silver London International Advertising Award and a Bronze and Silver Axis award in New Zealand.

She moved to Australia in 2000 and is happily married to her husband Oscar and has three beautiful children.
