Inevitably a friend, or even a relative (they can be different, you know), comes to New Orleans intent on enjoying the great cultural opportunities that we mostly take for granted. And along with the where-do-you-suggest-we-dine questions comes one that’s sometimes a stumper for locals: Where can we go to hear some good New Orleans music? Then you pause, you think, you wonder, and maybe you call one of your friends who spends more time in such pursuits than you. Frenchman Street comes up, maybe Snug Harbor, but, of course, you have no idea who is playing there. After that, the pickings seem to get slim. Who’s at Tip’s? House of Blues? Anywhere? Even if you settle on a place, there is a downside that has to do with the quality of the beverages. In many places, emphasis is placed on entertainment and not on cocktails or wine.
