HotHouse closed in July and the Jazz Showcase has been homeless since January, but even in the absence of two of the clubs that used to anchor the postfestival action, there’s plenty of after-hours music. The Velvet Lounge looks to be the most happening spot this weekend: Hard-bop drummer Dana Hall leads a quartet on Thursday, and on Friday and Sunday saxophonist Edward Wilkerson fronts his superb 8 Bold Souls–joined on Friday by guitarist Fareed Haque and on Sunday by New Orleans free-jazz saxophonist Ed “Kidd” Jordan, making his traditional festival-weekend visit. On Saturday night Jordan will go head-to-head with an old friend, Velvet Lounge proprietor and fellow tenor patriarch Fred Anderson; they’ll be backed by bassist Harrison Bankhead and drummer Hamid Drake.

Thursday is Elastic’s regular improvised-music night, and for festival week it features a double bill of the New Fracture Quartet (fronted by trumpeter Jaimie Branch and guitarist Dave Miller) and the Jason Stein Trio. At Weeds on Friday drummer Dave Marsalek leads his second afterfest jam with the Chicago Junglebop Syndicate, which he says plays real-time mashups of jazz standards and electronic dance music, “remixed, rearranged, and destroyed live.”

On Friday night at the Charleston, drummer Mike Reed debuts the new quartet People, Places & Things, with saxophonists Greg Ward and Tim Haldeman and bassist Jason Roebke. Its mission, says Reed, is to develop new arrangements of overlooked hard-bop tunes written in Chicago between 1954 and 1960; it’s also playing an open session Sunday at the Hungry Brain that’s likely to include personnel from Rob Mazurek’s Exploding Star Orchestra. On Saturday at the Brain, reedist Keefe Jackson leads a jam with members of Mazurek’s group and his own band Fast Citizens.

Uptown at DANK Haus, bassist Karl E. Siegfried hosts two very different nights of music: on Friday he’s joined by guitarist Joel Paterson and drummer Alex Hall for a program of early jazz, swing, and western swing, and on Saturday he plays a set with saxophonist Aaron Getsug and drummer Chris Avgerin that will “focus on the modern Chicago sound, blending hip-hop, jump, blues, and metal.”

At Heaven Gallery in Wicker Park, reedist David Boykin hosts his Hereafter Festival on Friday, Saturday, and Sunday. Each night begins with his Microcosmic Sound Orchestra, continues with the David Boykin Expanse, featuring flutist Nicole Mitchell, keyboardist Jim Baker, and bassist Josh Abrams, among others, and ends with a free-jazz jam session that will likely include a festival musician or three.
