Open Mics in Bismarck, ND

The sources give the same night and time, but none confirms recent activity.

The venue's own event listings show a recurring Blues Jam every Tuesday from 6 to 9 PM in the 1199 Speakeasy Lounge, with dated instances on Sep 1, 8, 15, and 22, 2026, hosted by Jennifer Lyn & The Groove Revival (checked Sep 7, 2026) [s1]. The Venue's Website also describes the Speakeasy Lounge [s2]. Its contact page lists the address as 900 S Washington Street [s3].

The sources disagree on the night.

The Venue's Website (checked Aug 14, 2026) says in present tense that open mic nights are the first Tuesday of each month, alongside live music every Friday and Saturday from 8 to 11 PM [s2]. This confirms the day and monthly frequency, though the specific format of the open mic is not stated on the page.
