Tavis, if as Marc Antony suggests you extend jazz to include blues, then you might want to try Tommy Chung's performances at The Wanch, in Wanchai. If you want a nicely dark dive, this is the place.
Tommy Chung has been double billed over recent months with Lamma's own Red Star Rising, BTW. Maybe Steve would like to add a bit of a self-promotion, here.
Chung is a legend, and not just in Hong Kong, but if you have a lot of dental work, some of it may fall out when you hear his stuff.
Another medical warning is that the Wanch is quite small, so in case the decibels start to be too much, I recommend taking a pair of earplugs. This is no joke.
They have an email list for the weekly schedules. The gigs are mainly rock cover bands, with only a few of the songs having stood the test of time. I mean, Big Wheels Alabama just doesn't do it for me, these days. Red Star resolutely refuses to do any covers.
Joyce should definitely check this place out, if she wants to learn what makes a music venue a music venue. The Wanch is a masterpiece of interior design.
Footnote: I checked the Wanch schedule at
http://www.myspace.com/thewanchhk, but unfortunately Chung isn't listed for June. Lamma's Steve Cray is, on 6/16 (in acoustic mode, apparently), and as Red Star on 6/19, and there's something called Blues Espresso on 6/27.
Chung has a website,
