In 1958, Murdoch was engaged by a Spanish dance theater and toured Australia as their international pianist under the name Jaime Sebastian. He toured with them in Europe, the United Kingdom, and elsewhere. He also assumed the conductor's podium for the company on the strength of his (untrue) claim that he had conducted student orchestras at the
Sydney Conservatorium. He composed two ballets for the dance troupe, one of which was
La Espera, which received 450 performances in Europe and Australia. After touring Australia in 1962 under his assumed name, he opted to remain in his home country. Murdoch became the assistant musical director and company pianist of the new
Australian Ballet company. From 1964 until 1968, he was deeply involved in the
World Record Club, which included the task of writing over 200 record cover notes each year. During the 1950s and 1960s, Murdoch was an active member of the
International Society for Contemporary Music, serving as secretary of its
Melbourne,
Sydney, and other Australian branches. In 1965, Murdoch directed the First Festival of Contemporary Music in Melbourne. Murdoch developed a tendon contraction through overuse of his hands and switched his career from being a pianist to being a concert promoter based in London. Among others, his company managed
Cathy Berberian,
Harrison Birtwistle,
Leo Brouwer,
Paul Crossley,
Peter Maxwell Davies, the Pierrot Players (later known as the
Fires of London),
Hans Werner Henze,
Igor Kipnis,
Roger Woodward, and the Budapest Chamber Orchestra. He was associated with the filmmaker
Ken Russell and assisted in organising the music for
The Devils and
The Boy Friend (both 1971). In 1973, Murdoch was the first musical adviser to the
Australia Council. In 1975, he was appointed to be the first National Director of the
Australian Music Centre (AMC), and in 1980, he was elected to be the world president of the Music Information Centre's Professional Branch. In 1981, Murdoch was sacked by the Music Board of the Australia Council, the funding body for the AMC, for what they perceived as inept financial administration. He was then rehired as a music consultant to the Australia Council but was dismissed again when they deemed his report on the state of music publishing in Australia as inadequate. He responded by suing the board for unfair dismissal, which later ended in an out-of-court settlement. Murdoch recorded 60 filmed interviews with leading writers, composers, and artists, now held at the
National Film and Sound Archive. He influenced composers like
Richard Meale and
Peggy Glanville-Hicks to return from self-imposed artistic exile overseas. After Glanville-Hicks died in 1990, he championed the Peggy Glanville-Hicks Composers Trust and Peggy Glanville-Hicks House, and he researched and wrote her biography,
Peggy Glanville-Hicks – A Transposed Life (2002). ==Chopin's walking stick==
