In 1962, the Melos Ensemble with Ellis released what is considered by musicologist Paul Loeber the finest rendition ever of Ravel's Introduction and Allegro,[1] playing with flautist Richard Adeney, clarinettist Gervase de Peyer, violinists Emanuel Hurwitz and Ivor McMahon, violist Cecil Aronowitz and cellist Terence Weil.

Their relationship began when Ellis was the harpist in a performance of A Ceremony of Carols in London on 4 January 1959, conducted by George Malcolm, which resulted in an invitation to play at the Aldeburgh Festival the following year.
