 single (1984) and Live Aid concert for Ethiopia in 1985, which, while successfully raising awareness of world poverty and funds for aid, have also been criticised (along with similar events), for providing a stage for self-aggrandisement and increased profits for the rock stars involved.Since its early development rock music has been associated with rebellion against social and political norms, most obviously in early rock and roll's rejection of an adult-dominated culture, the counterculture's rejection of consumerism and conformity and punk's rejection of all forms of social convention, however, it can also be seen as providing a means of commercial exploitation of such ideas and of diverting youth away from political action.Professional women instrumentalists are uncommon in rock genres such as heavy metal although bands such as Within Temptation have featured women as lead singers with men playing instruments.
