New Dia (Fenway) — Black Walls Gallery open mic

The venue's events page lists this night, but may not be current.

Weekly on Mondays, 7:00 PM. Only one source reports it.

The venue's own dedicated events page was last modified Jul 23, 2026, about three weeks earlier, confirming this art gallery inside a cannabis dispensary is real and currently maintained (checked Aug 13, 2026) [s1]. A search corroborates that the gallery hosts open mic nights generally, but the specific Monday 7pm slot could not be found on the page directly, so that detail stays unconfirmed. The gallery is 21-plus.
