Cliff Bell's

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

Press coverage describes an open jam session following booked sets at Cliff Bell's. The venue's own shows, home, and contact pages list only named, reservation-required acts and never use the words 'jam,' 'open mic,' 'sit in,' or 'after hours' (checked Aug 14, 2026) [s1]. The Venue's Website is clear about what is on its calendar but silent on any unadvertised open-signup component, so this is not resolved.
