The Historic New Orleans Collection’s galleries on Royal Street open onto one of the French Quarter’s most picturesque and historic interior courtyards. On spring and fall Fridays HNOC puts that courtyard to good use, presenting outdoor concerts by some of the city’s most accomplished traditional musicians. This month it’ll be the Dana Abbott Band. 6 pm–8 pm. Admission, which costs $10 and includes three complimentary beverages, places these concerts among New Orleans’ best-value evenings out. Even better value is a THNOC membership ($35 per year), since members get in free to all seven concerts in the series. Guests must be 21 or older to enter. hnoc.org or (504) 523-4662.
