EDM I suggest http://www.foundation-nightclub.com/
Jazz I suggest http://www.jazzalley.com/www-home/ (highly recommend)
R&B I suggest Emerald City Soul Club http://www.yelp.com/biz/emerald-city-soul-club-seattle?utm_campaign=www_business_share_popup&utm_medium=copy_link&utm_source=(direct)
Rock & Roll, head south to Tacoma and check out "The Swiss" or over in Freemont, "The High Dive"
We have a lot of Casinos here in the PacNW, most of them have clubs with weekend entertainment, one of the best is "Club Galaxy" in Auburn, south of Seattle off of Highway 18, Muckelshoot Casino. I think you'll really enjoy this place, large professional stage, both DJ's and bands, depending on the night. Think "Earth, Wind & Fire" great cover bands here.
There are a lot of hole in the wall places as well in Pioneer Square, Belltown, and if your hip to the LGBT scene, head to Capitol Hill, couple of great dance clubs there as well. Now if you want trendy, head over I-90 to the Eastside to Bellevue.
The PacNW nightlife is FAR from dead, but of course it's not Miami, LA or NYC, have a great time while you're here!
radarvectors (DJ with over 30 yrs exp)....OH yeah, there are Salsa clubs as well, just do your homework.
