Yothu Yindicannot be put into the watered-down, new-age inspired "world music" category despite the aboriginal background of most band members. There are no synthesizers backing up a few notes on some "indigenous" instruments here; "Tribal Voice" is not easy listening. Instead, it's hard-hitting, full-throttle rock, with a powerful merger of aboriginal (esp. the didgeridoo) and more conventional instruments. The result is some really fresh and unique music that can't quite be compared to anything else - not even fellow Aussie rockers Midnight Oil, even though their political stance is quite similar. Yothu Yindi has done a great job of skillfully melding traditional sounds with rock and a relevant message.
