Tonight was supposed to be the online Wednesday in March with nothing on the official schedule for the Washington Women in Jazz Festival—-Twins Jazz was already booked.

But no! Festival organizer Amy K. Bormet conspired with Giovanni Russonello and Luke Stewart, the jazz advocates behind CapitalBop, to pencil in a special bonus session at their preferred performance space, the Red Door loft, tonight. Unlike the Twins performances, it’s a one-acter—-think of it as the WWJF all-stars. Bormet herself will be behind the piano and microphone, joined by fellow singer Integriti Reeves, no-longer-pneumonic bassist Karine Chapdelaine, drummer Andrew Hare, and, for an unusual bit of flavor, tap dancer Melissa Frakman. They work from 8 to 10 p.m., at which time—-in the CapitalBop way—-an open jam session takes control.

The Red Door is at 443 I St. NW. A $10 donation is suggested, and the show is BYOB. Musicians, bring your horns!
