On Saturday, Sarah Jane and the Blue Notes (pictured) will host an evening of music on the rooftop of the Deco Fortress, a restored vintage building that doubles as singer Sarah Ulrich's not-so-secret HQ. (See also: the Fantastic Four and the Baxter Building, the Avengers and Avengers Mansion, etc. The event also apparently will serve as a release party for the group's new CD, though we can't tell you any more than that, because our request for more details yielded no response.)
Update, 2:25 p.m. 7/10/13: Seemingly within seconds after pushing the publish" button on this post, yr. humble editor received a missive from the aforementioned Ms. Ulrich. The CD is titled simply Sarah Jane and the Blue Notes, and includes seven tracks featuring their interpretations of vintage tunes including Them There Eyes," Gee Baby, Ain't I Good To You" and Bei Mir Bist Du Schoen." The album was recorded by Ulrich and a six-piece band, then mixed and mastered, all in the home studio of Sam Olhausen.
Also on Saturday, the jazz/electronic/new music ensemble Koplant No will deploy their various devices at Tavern of Fine Arts; and singer Ann Dueren's trio is at Il Bel Lago.

Meanwhile, the St. Louis Record Collector and CD Show's summer event also takes place on Sunday in the usual location - the American Czech Hall at 4690 Lansdowne on the south side - and the St. Louis Jazz Club will present the cryptically named Time and Place in a matinee performance at Bel-Air Bowl in Belleville.
Looking beyond the weekend, on Monday trumpeter Keith Moyer brings his group back to BB's Jazz, Blues and Soups.
