Blue Earth Sound is the instrumental world of Chicago-based multi-instrumentalist and composer James Weir — a project that moves like a late-night film scene, blending cinematic jazz, soul, and psychedelic textures into immersive, atmospheric soundscapes. Named for Weir’s roots in Blue Earth County, Minnesota, the moniker carries a sense of place, but it also hints at the way this music is made: in conversation, in community, and in the moment.

Weir introduced Blue Earth Sound with his debut album Cicero Nights (Root Records), an eight-track suite inspired by after-hours city wanderings. Recorded with a cast of Chicago collaborators — including International Anthem engineer Dave Vettraino and Resavoir trumpeter Will Miller — the record established his palette: hypnotic grooves, dusty keys, and instrumentals that feel both expansive and intimate, like memories you can walk through. Now, Weir returns with The St. Louis Sessions, arriving Friday, 19 June via DeepMatter Records — a collection of recordings that documents a spontaneous creative moment shared with friends and long-time collaborators in St. Louis, Missouri. At the centre of it all is the newly built home studio of drummer Austin LeMoine, a space that became less a “facility” and more a living, breathing room where instinct led, and the tape rolled.

Visiting St. Louis from Chicago, Weir arrived with a handful of demos — sketches meant to be tested, stretched, and reshaped. The sessions took on a life of their own when LeMoine tapped into the local scene, inviting brass players Jawaad Spaan and Josiah Burton into the mix.
“As soon as we got set up, Austin was hip to some local brass players, Jawaad Spaan and Josiah Burton, from the St. Louis scene that we invited over for an experimental session tracked in his living room,” Weir shares. “After bonding over shared taste and drinks, we recorded the horn takes live together over my demos.”

That relaxed, inspired energy is exactly what you hear on The St. Louis Sessions. The EP captures the warmth of musicians sharing a room and following their instincts — balancing trance-like rhythms, soul-leaning arrangements, and late-night reflection with the kind of spontaneity that can’t be manufactured. Where Cicero Nights opened the door to Blue Earth Sound’s cinematic universe, The St. Louis Sessions feels like a closer shot: an intimate snapshot of the project in motion. Spaan and Burton’s horn arrangements become a defining voice across the release, moving fluidly between improvisation and carefully curated post-production. There’s a lived-in quality to the sound — grooves that settle into your chest, textures that drift like smoke, and melodies that arrive with quiet confidence.

Lead single “Chartreuse” emerged while the group was still learning the ins and outs of the new studio set-up. Built around a trance-inducing rhythm section and drifting guitar lines, the track was later reshaped in post into a hazy, layered groove — a perfect introduction to the EP’s “caught in the moment” spirit.
Follow-up single “Japanese Green” leans into the influence of Japanese jazz and ’90s R&B, pairing swinging Wurlitzer chords with tightly unified horn melodies and a low end that keeps the track moving with warm, cruising energy.
.
The EP’s focus track, “Fresh Air,” might be the purest expression of the sessions’ collaborative heart. Built from a guitar demo that was later harmonised and expanded with horns, the groove nods to classic J Dilla samples — and the track was constructed in reverse, with horn parts recorded first before the rest of the arrangement was built around them. The result is open and breathing, like the music is unfolding in real time.
The St. Louis Sessions drops Friday, 19 June, via DeepMatter Records.
