well if your thinking about moving to SF there is a good collection of artists in and around the area. The reason why you don't see Techno in the clubs up here is because most techno parties are really underground and for the older rave crowds and are hush hush in a way.
though there are the occasional parties and clubs that go on
Heres a few of the local artists and promoters you might want to search for:
Omniscent Records - Praxis
Resource Records - Chris Jackson
DEFSF - Dj Disconnect
we ourselves do Techno Events and have a forum @:
www.techno-truth.com
www.stilldream.org
and have had Chris, Aaron, Julian, Ant, DDR, Rackit, Sarah FAB and a few others out over the last couple of years.
Best of Luck to ya, hit me up before you come out this way.
