Some music does not belong to a genre so much as to an afternoon: the cooler is open, somebody's uncle is on the grill, and this is what has been playing underneath every one of those days for fifty years. Half a century of it, from Honolulu out to every backyard in Southern California that ever hosted a luau nobody planned properly. The anniversary show brings that catalog to the vineyards outside Temecula, and the crowd it pulls is the whole point — the Hawaiian-music community here turns out for this band the way you turn out for family. Bring a bottle and your most unhurried self. Somewhere between the second song and the sunset you stop checking your phone, and then you notice everyone around you already had. Send it to the person whose house always smelled like that on a Sunday.
