A listing on badslava.com lists this night, but may not be current.
The only listed source for this listing is an open-mic listing site [s1]. Other descriptions of the venue mention only booked live jazz on Friday evenings and Saturday lunch, never an open-signup event. The Venue's Website could not be reached, which is not evidence either way (checked Aug 14, 2026).
The venue's current events page states 'Open Mic Night -- Every 2nd Thursday' (checked Aug 14, 2026) [s2]. This corrects an earlier weekly description to monthly. It describes the event only as an 'open mic and jam,' not a specific format; unverified 2024-2025 descriptions call it a bring-your-own-instrument jam, consistent with but not proof of a music-only format.
