ok, i've been lurking in this post for a while and i'm a hongkonger. let me explain the situation to you.
we've got the same show last year. some SM acts and two local bands were invited. the two local bands were accused of not being sensitive towards the political scenario, especially one of the local bands was praised for voicing out the inequality in society through their music. their participation quite opposed to the public's will and expectations. that's why no local acts dared to join the show this year. it's basically a suicide to their career.
pretty disappointed that infinite joined this year's show but glad that no one really cares about the foreign acts.
