Both sources give the same night and time, but neither confirms recent activity.
An open-mic listing site's full listing gives a Saturday start time of 7:00 PM and describes it as a weekly music night, free to attend (checked Aug 13, 2026) [s1]. A different listing site instead tags the same venue as a comedy event [s2]. Other sources give an 8:00 PM start with a different phone number; neither the type nor the exact time is resolved, and no website was found for the venue.
A review on yelp.com lists this night, but may not be current.
Weekly on Thursdays, 7:30 PM. Only one source reports it.
No website was found for the venue. A review site describes La Clave as New Rochelle's leading night club, open Thursday through Saturday, 10 PM to 4 AM, with DJs, live music, and karaoke, and does not mention an open-signup music open mic (checked Aug 2026) [s2]. An open-mic listing site separately claims a Thursday 7:30 PM open mic here [s1]. That may not match the night club's late-night format, or may be outdated.
