The roots music non-profit is presenting a stellar show this evening at the Mid City Lanes Rock ‘n’ Bowl.  Dubbed “A Congo Mambo,” the concert features left-handed guitar burner Barbara Lynn (pictured) and Southwest Louisiana’s own guitar slinger, Lil’ Buck Senegal.  The Ponderosa Stomp, which traditionally has occurred during the week between the two weekends of the New Orleans Jazz and Heritage Festival is moving to the last weekend in September.  Tickets are already on sale for the shows at the House of Blues.
