September has excellent taste. It favors an extra layer after sunset, something acoustic drifting across a campground and a meal whose preparation began while everyone else was asleep. Across bluegrass and barbecue this week, the people responsible for those pleasures are giving American tradition a thoughtful tuneup, even as the cost of keeping the fire going becomes harder to ignore.

Start in Buena Vista, Virginia, where the Nothin’ Fancy Bluegrass Festival reached its 24th year with a potluck, campground games and a lineup including Rhonda Vincent, The Grascals and Authentic Unlimited. There is something wonderfully civilizing about a festival where your contribution might involve both a guitar solo and a casserole. The shared meal helps explain how these gatherings endure. People return for friendships that have acquired their own annual calendar.

The host band also supplied an ideal soundtrack. Nothin’ Fancy’s new version of Nanci Griffith’s Love at the Five & Dime carries her story of young love and working lives into a bluegrass arrangement. Griffith understood the emotional geography of ordinary American places, the counters, dance floors and cheap rooms where people assemble a life. Her writing gives a seasoned acoustic band plenty to work with, allowing the story to travel comfortably through another musical neighborhood.

Other musicians are widening the repertoire with similar confidence. AJ Lee & Blue Summit’s Cover to Cover draws on the songs that shaped the group, ranging across bluegrass, country, pop and jazz. Lonesome River Band brings electric guitarist Rod Riley into Hit the Nail on the Head, placing a bluesier edge alongside Sammy Shelor’s banjo. The appeal lies in hearing experienced players make room for another voice while keeping the ensemble moving.

That sense of continuity gives Dudley Connell’s forthcoming Washington Monument Award particular resonance. The DC Bluegrass Union will honor a career that stretches from the Johnson Mountain Boys through roughly three decades with The Seldom Scene. Connell offers a reminder of the capital region’s substantial bluegrass history, sustained by musicians and audiences across Washington, Maryland and northern Virginia. Americana has always flourished in places that complicate its postcard image.

Down in Texas, the conversation around another cultural institution has become considerably more expensive.

Butter’s BBQ in Sinton, a Texas Monthly Top 50 restaurant, announced it would stop serving brisket, saying the cut accounted for more than 70 percent of its grocery expenses during a difficult sales year. Pork ribs, turkey, sausage and Sunday barbacoa remain part of its future.

For a Texas smokehouse, removing brisket is a consequential editorial decision. The meat has become the centerpiece of the contemporary barbecue pilgrimage, photographed in glistening slices and discussed with the attention usually reserved for vintage watches. Its preparation demands fuel, labor, skill and a willingness to watch a substantial portion of the purchased weight disappear during cooking. Admiration pays only so many invoices.

Kelly’s Hill Country BBQ in Wimberley has also announced plans to close under financial strain. Meanwhile, Terry Black’s has opened its eighth location in New Braunfels, complete with a two-story outdoor deck and substantial smoking operations. Taken together, these developments show how much the experience on the tray depends on the resources behind the counter.

There is fresh energy elsewhere in the business. In Your Smokin’ Face, a family-owned seasoning company from Roma, reached the finals of H-E-B’s Quest for Texas Best competition with products including an orange pepper piquin blend and a carne asada rub. South Texas flavors have an opportunity to reach a wider grocery audience, carrying the character of a particular place onto somebody else’s weeknight dinner.

Equipment makers, meanwhile, are concentrating on the small irritations that accompany big cooking ambitions. A Blackstone patent filing describes a mechanism that agitates pellets inside a hopper to help keep fuel feeding consistently. It remains a proposed system, though anyone who has supervised an overnight cook will understand the attraction. YETI’s stated interest in enameled cast iron suggests that the premium outdoor lifestyle may soon occupy even more kitchen cupboard space.

The most appealing thread through all of this is the human one. A band finds new possibilities in an old song. A young ensemble absorbs its influences. A pitmaster changes the menu to keep the doors open. These traditions ask a great deal of the people who sustain them, and their future depends on audiences willing to show up, listen closely and order lunch.
