Performing arts of Australia  The Performing arts in Australia are an important element of the Arts in Australia and Australian culture. Dance in Australia is diverse, ranging from The Australian Ballet to the Restless Dance Company to the many local dance studios. Aboriginal song was and remains an integral part of Aboriginal culture since time immemorial. The most famous feature of their music is the didgeridoo. This wooden instrument, used amongst the Aboriginal clans of northern Australia, makes a distinctive droning sound and its use has been adopted by a wide variety of non-Aboriginal performers. Aboriginal musicians have turned their hand to Western popular musical forms, often to considerable commercial success. Some notable examples include Archie Roach, the Warumpi Band, NoKTuRNL and Yothu Yindi. Australia has produced a wide variety of popular music. While many musicians and bands (some notable examples include the 1960s successes of The Easybeats and the folk-pop group The Seekers, through the heavy rock of AC/DC and the slick pop of INXS and more recently Savage Garden have had considerable international success, there remains some debate over whether Australian popular music really has a distinctive sound. Perhaps the most striking common feature of Australian music, like many other Australian art forms, is the dry, often self-deprecating humour evident in the lyrics. Until the late 1960s, many have argued that Australian popular music was largely indistinguishable from imported music: British to begin with, then gradually more and more American in the post-war years. The sudden arrival of the 1960s underground movement into the mainstream in the early 1970s changed Australian music permanently: Skyhooks were far from the first people to write songs in Australia, by Australians, about Australia, but they "were" the first ones ever to make money doing it. The two best-selling Australian albums ever made (at that time) put Australian music on the map. Within a few years, the novelty had worn off and it became commonplace to hear distinctively Australian lyrics and sometimes sounds side-by-side with the imitators and the imports. The national expansion of ABC youth radio station Triple J during the 1990s has greatly increased the visibility and availability of homegrown talent to listeners nationwide. Since the mid-1990s a string of successful alternative Australian acts have emerged – artists to achieve both underground (critical) and mainstream (commercial) success include silverchair, Grinspoon, Powderfinger and Jet. The first Australian musician of any sort to achieve international fame was operatic soprano Nellie Melba, in the late 19th century.
