Like many artistic platforms in Hong Kong, the problem for Hidden Agenda is using industrial premises. The government doesn’t see music as industry and a couple of months ago told them to desist. It seems they've never heard of Justin Bieber - he’s an industry in himself.

The manager, Kim Lam, has refused to bow to the pressure. The wider concern is that if the government can close Hidden Agenda they can close down Hong Kong’s other indie bands also based in factory buildings – 80 percent of which are in Kwun Tong.

Tickets for the festival cost HKD100 for one day or HKD150 for the whole weekend with performances starting at 4pm. There’s a wide range of local talent on show, playing everything from metal to experimental and hardcore to indie, with key sets from An Id Signal and King Ly Chee. Because of the diversity on offer, you’ll have to refrain from tearing into music you normally take offense to – or step outside for long periods of time.

Be Greek for the day – protest, loudly.
