James Blood Ulmer, whose aggressively avant-garde guitar compositions demolished the boundaries separating jazz, funk, punk, blues and even country music, earning him comparisons to Jimi Hendrix, guitarist Wes Montgomery and his mentor, saxophonist Ornette Coleman, died on June 3 in New York City. He was 86. In a statement, his family said that the death, at a care facility, was from cardiac arrest.
