When the jazz gods close the door, they open a window. The music’s primary outlet in Northeast D.C., HR-57, closed in August, but the Jazz And Cultural Society, or JACS, had its soft opening in Brookland on Nov. 13. Trumpeter DeAndrey Howard, the visionary behind JACS, named it carefully: He sees it as a cultural society rather than a club, albeit one with jazz at its center. His vision is of a place where older musicians can have a showcase, where younger cats can learn from them, and where audiences can observe it all for low cover charges. The soft opening, featuring Howard and a handful of other local musicians, made for a wildly successful evening—but maintenance issues in the long-dormant building have delayed its grand opening until at least January.
