The Venue's Website appears not to mention 'Monday' or 'open mic' [s1]. A later check (Sep 5, 2026) found the site returns the same content no matter what page is requested [s2]. That means the earlier silence can't be trusted as real evidence. The only dated corroboration found is a calendar listing from Dec 2, 2024, about 21 months earlier, so the status is held to unknown, at low confidence.
A listing site read on 2026-09-25 disagrees with the Thursday night here: badslava.com lists Tuesday 8 PM, record has Thursday. Which is current is unresolved — check before travelling. Something about this has changed recently — confirm before going.
Call to confirm the night
The sources disagree on the night.
Several venue-adjacent mentions (a review site, social media) describe a Thursday 8pm event here, consistent with an earlier finding, but the venue's own page remains unreachable due to a persistent connection error. Signup is by emailing in advance rather than a walk-in list, raising an unresolved question about whether this counts as open-signup. A day-of-week contradiction between Tuesday and Thursday claims remains unresolved.
Night and frequency are unclear — no source gives either.

The sources list this event, but none confirms recent activity.
As of Sep 1, 2026, a regional comedy open-mic listing remains the only source naming this comedy open mic [s1]. A review site could not confirm anything further [s2]. A newly found web address confirms the exact address and business name -- the right venue -- but it's only a simple link-in-bio page with no event listings, so its silence means nothing [s3]. No other source corroborates the mic.
A post on instagram.com lists this night, but may not be current.
Weekly on Wednesdays, 7:00 PM. The Venue's Website has gone offline since we found this.
As of Aug 31, 2026, the Venue's Website gave the same error page on every path tried, consistent with a lapsed domain. A promoter's social media account describes 'Open Mic & Karaoke' here, but the only dated post is from March 14, 2025, about 17 months earlier, well beyond what would show a weekly event is still running [s1]. A listing site reconfirms Wednesday but carries no date.

No new check was made; an earlier full read of the venue's own current website found no mention of 'open mic,' and no other source has ever corroborated this claim. This is a 1,500-plus-seat touring theater, a venue type ill-suited to a weekly open-signup mic -- this likely reflects a data error about the wrong kind of venue.

A bluegrass association's own dated post, from Jan 19, 2026, states 'Riverside, CA: Saturdays from 9-noon Inland Empire Bluegrass Jam at Fairmont Park,' with a Beginners Jam Academy 9-10 AM followed by open jam 10-noon [s1]. This post is about seven months old as of Aug 31, 2026, slightly past the usual six-month recency guideline for a weekly event, so confidence is held at medium rather than high.
A listing on badslava.com lists this night, but may not be current.
Weekly on Thursdays, 7:00 PM. Only one source reports it.
As of Aug 31, 2026, the venue's own events page could not be reached again. A general description of the venue's live-music programming (live music Friday and Saturday, karaoke other nights) doesn't mention a Thursday open mic, which is suggestive but not treated as a firm negative, since it wasn't drawn from a full event listing.
Both sources list this event, but neither confirms recent activity.
This location's own page shares the chain's boilerplate monthly-schedule wording (checked Sep 1, 2026) [s1]. That wording matches the Norco page, so the monthly schedule is shared marketing copy, not verified for this address. The page also carries a location-specific street address and a working sign-up form, suggesting upkeep beyond the shared copy [s1]. The chain's location list still shows this one as active [s2].
