Technically, and speaking in a grander scheme of things, the best night to be in Deep Ellum is when every single one of those annoying roof decks catches fire, when those hovering meat markets that serve as an unfortunate nexus of silicone, tanning beds, bleached blondes, leather pants, green apple martinis and Young MC fill the sky with the acrid smoke of bad taste gone ablaze. Failing that, Thursday is the night to be in Deep Ellum, with fewer gawking tourists--and as far as we're concerned, that includes anyone north of LBJ--and more good shows. Club Clearview, Liquid Lounge and Curtain Club usually have three-band bills without a single hole in the lineup, and Trees hosts a weekly showcase by B.I.O. (Base Intelligence Organization) that features DJs and electronic music acts and all sorts of experimental fare. One way or another, you'll find something you like, and you won't have to wade through a sea of SUVs and their South Beach-wannabe drivers to do it. Let them have the weekends.
