They’re more “Pretty Vacant” than “White Riot.” An underground punk music scene has swelled within the capital of Myanmar — and there’s much to rebel against. Citizens faced strict censorship and political oppression for decades under the military dictatorship, and under the new quasi-democratic government, the censorship’s voluntary, but expected. In the West, punks rebelled against societal norms. But in Myanmar, these rockers’ dissatisfaction is mainstream, finding allies — or at least sympathy — across a wide range of groups. With real change uncertain, all they can do is keep rocking.
