The recorded catalog of the duo known as War & Pierce is small but mighty.

There’s a self-titled, six-song EP that came out early in 2016, followed by a smattering of singles with names like “Amen” and “Mercy” that seem to tell the tale of the time they were released — the turbulent years of 2020 and 2021.

And that’s about it. Invariably, these tunes are beautifully moving examples of acoustic roots music from the Black perspective, wherein folk, blues and soul gently coalesce into a sound that feels both weightless and weighty at the same time.

That’s the small part. Here’s the mighty part: War & Pierce isn’t just any musical duo. The “War” in question is Sunny War, a Los Angeles-based singer-songwriter with roots in the city’s punk underground. And “Pierce” is War’s fellow Angeleno, Chris Pierce, an open-hearted troubadour who is closing in on 30 years as a working musician.

It would be inaccurate to say War and Pierce were unknowns when they released “War & Pierce” back in 2016; each had carved out their own space by then. It would not be inaccurate, however, to say that both have spent the past couple of years on an upward trajectory and are much better known now as solo artists than they ever were as a team.

Which makes the work of War & Pierce feel like both a bit of a secret (it’s not) and a fascinating artifact from another time (maybe it is). Listening to the music War and Pierce have made together is sort of like watching the old cartoon superhero duo, the Wonder Twins, activate their powers in reverse: They are potent as a team, but as individual solo artists, it feels as though they’ve been unleashed and allowed to blossom into their fully realized, formidable selves.

Both are coming off banner years. Sunny War’s “Anarchist Gospel” — a collection of riveting blues ‘n’ more tunes released on indie-roots giant New West Records — was one of the best albums of 2023, touted by the tastemaking website Pitchfork for its warmth, empathy, “expansive, considered sound” and “quietly idiosyncratic style.” (Rolling Stone called War “One of the Best New Voices in Roots Music.) Besides Pierce, she’ll tour with Bonnie Raitt and Mitski this year.

Pierce also released a new album last year. Released in September, “Let All Who Will” is an effortlessly soulful, deeply thoughtful, endlessly tuneful and exquisitely crafted set of songs that roots-music bible No Depression praised as “anthemic in their scope, yet intimate and personal in their focus.” Central Oregonians might have seen Pierce perform live in 2023, too; he was handpicked to open Neil Young’s first tour in four years, which made a stop at Bend’s Hayden Homes Amphitheater on July 17.

Now, he’s headed back to the region, this time for a show Friday night at The Belfry in Sisters, and with Sunny War joining him on the bill. Will they play War & Pierce songs? Seems likely, but who knows for sure? (They do, but I don’t.)

More certain: This will be one of the best double bills of the year ‘round these parts, and in an incredibly intimate place to see a show. Don’t miss it.
