Chicago’s September 3–6 music calendar has a useful after-dark thread for listeners who want to follow jazz beyond one formal concert slot. The route begins Thursday, September 3, with a two-set Mario Abney engagement at Andy’s Jazz Club, shifts into Brian Citro’s late-night guitar-led program in the same room, carries into the Green Mill Jam Session with Marquis Hill at 1am Friday, September 4, and closes Sunday, September 6, with Sound Obsession and DJ Zipgun Boogie at Dorian’s. It is a small itinerary built around changing contexts: a working quintet, a late trio, an open jam, and a DJ’s selection of scores and oddities.[1][2][3][4]

A Thursday sequence at Andy’s Jazz Club

The cleanest entry point is Mario Abney’s 6pm set at Andy’s Jazz Club. Abney returns for a second set at 8:15pm, creating a chance to hear the same Mario Abney Quintet across two compact evening performances. The club describes the Chicago-born trumpeter’s approach as a fusion of traditional and extended techniques, an apt detail for a player whose work makes sound color and exchange central to the presentation. Either set works on its own; together, they give Thursday a deliberate, unhurried opening.[1]

At 10:30pm, guitarist Brian Citro takes over Andy’s Jazz Club’s Late Night Concert Series. Citro’s official listing identifies an organ-trio lineup with Tom Vaitsas on keys and Peter Mack on drums, and frames the program around Citro’s compositions alongside material associated with Pat Metheny, Frank Ocean, Todd Rundgren and Carole King. That breadth gives the late slot its own frame after Abney’s pair of trumpet-led sets, while keeping the entire evening inside a single room.[2]

The jam-room turn at Green Mill

For the listener extending Thursday into Friday morning, the Green Mill Jam Session with Marquis Hill begins at 1am on Friday, September 4. Green Mill has revived late-night Friday programming around Hill’s jam, with a listed $5 cover and a run into the early hours. The point here is the change in format: after two ticketed club presentations at Andy’s Jazz Club, the Green Mill offers a session built around a host and the live, communal logic implied by a jam. Plan the night around the 1am start, and leave room for the clock to move.[3]

Sunday scores, soundtracks and oddities at Dorian’s

Dorian’s provides the Sunday landing point at 8pm with Sound Obsession and DJ Zipgun Boogie. The venue bills the event as free, 21+, and centered on selections from Zipgun Boogie’s library of soundtracks, scores and oddities. It sits at the outer edge of this jazz thread, where listening practice and recorded music take priority over a bandstand. Recheck the official pages for set times, entry details, prices and any last-minute changes before heading to Andy’s Jazz Club, Green Mill or Dorian’s.[4]
