The Plaquemine Four is less a band, more a New Orleans jam in full swing. Every 1st and 3rd Saturday, a fresh mix of hot young jazzers, surprise guests, and brass-toting regulars blow the roof off with trad standards, funk-inflected grooves, and moments of pure chaos. It’s the kind of night where you come for one song and stay for two sets — no setlist, no guarantees, just the raw joy of live improvisation. Anything could happen, and it usually does.
