The primary exponent of harmolodic guitar and a foundational figure in the free funk movement, James Blood Ulmer died on June 3, 2026, at the age of 86. A fearless composer and performer, he was best known for translating avant-garde jazz theories into a jagged, electric language that bridged the gap between the delta and the stratosphere.

Born Willie James Ulmer in rural, segregated St. Matthews, South Carolina, he grew up as the eldest of eight children in a home where the sacred and the secular pulled against each other. His father, James David Ulmer, a Baptist preacher, gave him his first guitar at 4, and the first professional music he made was singing gospel with his father’s vocal quartet, the Southern Sons. That early split stayed with him. As he later put it, “We had two kinds of blues: one that was forbidden, and one that wasn’t.”

At 18, he left for Pittsburgh and entered the rougher, more public world of doo-wop and R&B, performing with groups including the Del Vikings and the Savoys. The move widened his musical vocabulary without softening his instincts. In the years that followed, he worked in Columbus, Ohio, from 1964 to 1967, recording with organist Hank Marr, then relocated to Detroit in the late 1960s, where he taught music and played in Focus Novii with drummer Doug Hammond. Those stops mattered less as destinations than as pressure points, places where his playing kept hardening toward the sound he would later make in New York.

He arrived in New York City in 1971 and held a residency in the house band at Minton’s Playhouse in Harlem, where the city’s creative density gave his ideas room to snap into focus. He became the first electric guitarist to record and tour extensively with Ornette Coleman, a partnership that made him the first to translate Coleman’s harmolodic theory into an electric guitar language of his own. To fit that approach, he developed a tuning in which all six strings were set to the same note, a technical choice that helped him turn the instrument into something less like a chord machine than a single, volatile engine.

By the late 1970s, Ulmer had begun to define his own center. His debut album as a leader, Tales of Captain Black, came out in 1978 and was co-produced by Coleman. Two years later, Are You Glad to Be in America? became a signature work, folding social commentary into avant-garde funk without sanding off any of its edges. Robert Palmer called him “The most original electric guitarist to emerge since the late Jimi Hendrix,” and the comparison fit not because Ulmer imitated anyone, but because he treated the guitar as a site of rupture, not polish.

The early 1980s were his Black Rock era, and he pushed it with the same refusal that had shaped his earlier work. Signed to Columbia Records, he released Free Lancing in 1981 and Black Rock in 1982, then formed Odyssey The Band with violinist Charles Burnham and drummer Warren Benbow, debuting the group on Odyssey in 1983. He also took his music onto rock and post-punk bills, opening for Public Image Ltd and Captain Beefheart, and he did not pretend to be there to win over the crowd. “I’d stand at the microphone and tell them to shut the fuck up,” he said. “They had five minutes to get into it or get the fuck out!”

That bluntness was not a pose so much as part of the method. Ulmer’s music insisted on its own terms, and he spent decades building a bridge between high-art experiment and the bodily pulse of American roots music. “Jazz is the teacher, funk is the preacher,” he said, and the line captured the whole arc of his career, from the gospel quartet in St. Matthews to the electric, uncompromising sound that followed him through New York and beyond. He is survived by his children, Greg, Donna and Michael.
