Hey, am stopping by.

Space closed down and was promptly replaced by a venue called Happy, which I think may just be Happy in a different location. It opened since I left NZ, so haven't been there either. Omaar? bleep?
Birchville Cat Motel is a guy called Campbell Kneale who does sorta noisy drone / shards of cold vibes stuff on a laptop, coming from a background of guitar noise. I think!? Shit, beats me. Friends I know who are more into the rock than the dance think he makes a great racket. He has a CDR label called "Celebrate Psi-Phenomenon".
Happy's owner, Jeff Henderson, has some free music on this Kiwi net label:

He's a free improv saxophonist.
If a group called The Labcoats happen to be playing I think it'd be well worth checking out. I dunno, probably a few interesting things going on at that place if you like stuff rough and loose, rather than smooth or glam.
I'm trying to think of any music by Wellingtonians you might've heard. I guess Recloose fits the bill now - pretty sure he has a residency at Matterhorn? You know, was on Planet E, Detroit techno guy..? Otherwise in recent times there's a guy called Signer who has releases on New York's Carpark, and Andrew Thomas on Cologne's Kompakt, but I don't know if either of them play out.
What's the rough ballpark of your interests anyway? There's heaps of sorta nu jazz / mellow breaks / reggae / soul / we love Giles Peterson-ness going on most of the time.
