A beer will be enough!
I've got the same problem. I moved here in October and I'm bummed for a city this size there aren't more touring acts coming through. If you find a decent beer bar with a jukebox let me know. A friend recommended Hong Kong Gig Guide on Facebook if you are looking for shows:

Dunno about clubs but Heavy Hong Kong and True Skool put on reggae and dancehall events in HK. I think there may be something on this weekend.
