Australian music has had lots of world-wide stars, for example the opera singers Nellie Melba and Joan Sutherland, the rock and roll bands Bee Gees, AC/DC and INXS, the folk-rocker Paul Kelly (musician), the pop singer Kylie Minogue and Australian country music stars Slim Dusty and John Williamson. Australian Aboriginal music is very special and very ancient: it has the famous digeridoo woodwind instrument.
