The Aborigines of northern Australia have likely been playing didgeridoos for more than 100,000 years. This Friday, when The Queensland Orchestra performs at the Festival of Asian Orchestras in Tokyo, it will be the haunting sound of this instrument that first reaches the ears of the audience. Behind the instrument will be 21-year-old William Barton, who was raised as a tribal Aborigine in the northwestern Queensland mining town of Mount Isa and is fast becoming Australia's leading "didj player."

Barton is soloist in new versions of "Mangrove" and "Earth Cry" by Australia's leading composer, Peter Sculthorpe. Sculthorpe, 73, was a close friend of Toru Takemitsu, who, until his death in February 1996 at age 65, was the international voice of Japanese contemporary concert music. In his own music, Sculthorpe is the Australian counterpart of Takemitsu, having -- since the mid-1960s -- opened Australian music to the sounds of Asia, and to Japanese culture in particular.

Composed in 1986, "Earth Cry" was intended as a kind of wake-up call to an increasingly commercialized culture, with Sculthorpe urging us "to listen to the cry of the Earth, as the Aborigines have done for many thousands of years." When he encountered Barton at a Queensland Orchestra concert in Brisbane a month ago, he decided to add parts for didgeridoo, both for this piece and "Mangrove."

The 83-member Queensland Orchestra, formed two years ago through an amalgamation of two separate orchestras, is led by Australia's youngest orchestra conductor, Michael Christie, a 28-year-old American appointed last September. For Friday's concert, in addition to the Sculthorpe compositions, he will lead the orchestra in Sibelius' Symphony No. 2 and Tchaikovsky's First Piano Concerto, with young Sydney pianist Andrea Lam.

In its two years, "the first orchestra of the 21st century" has performed for the state opera and ballet companies, for schools and festivals in more than 180 concerts throughout a state larger than Texas. It has also embarked on more adventurous programming and collaborations with a rock group, a tango school, an aerial circus and its local chapter of the Hell's Angels. However, central to its new identity is its focus on the Asia-Pacific region, and this first visit to Japan marks a symbolic first step in that direction.
