Bob Belden

NEW YORK — Bob Belden, a Grammy-winning jazz musician, composer, arranger and producer who was the first American musician to perform in Iran since its 1979 revolution when he toured there earlier this year, died Wednesday. He was 58.

Belden died at Lenox Hill Hospital in Manhattan after suffering a heart attack in his apartment, his sister Elizabeth Belden Harmstone said. She described her brother as a pioneer and a “jazz musician true and true.”

In February, Belden and his group, Animation, went on a four-day tour of Iran, performing tunes by Miles Davis, Herbie Hancock and Belden’s own compositions. The visit came as Tehran and Washington engaged in nuclear talks.
