“She was a true collaborator, and that’s why she was so damn good at playing this music,” said the Brooklyn composer and vocalist Amirtha Kidambi, who began improvising with Ms. Branch soon after she arrived in Brooklyn. “She could listen, give and receive in equal measure with an unparalleled generosity. She had so many extremely close friends who also were collaborators, and because of that she wanted each individual to be really strong and strengthen the community as a whole.”
In addition to her sister, Ms. Branch is survived by her mother and two half brothers, Clark and Russell. Her father died in 2017; the first Fly or Die album was dedicated to him.
Ms. Branch had recently finished mixing Fly or Die’s third studio album. Ever seeking new sounds, she was also discussing potential projects like dub remixes of Anteloper and exploring her interest in the Chicago electronic dance music genre known as footwork.
“A lot of her collaborators were jazz musicians,” said Piotr Orlov, a friend and supporter who wrote the liner notes for the 2021 album “Fly or Die Live,” “but ‘the music’ for her was much broader, always filled with rhythm for moving, improvisation for keeping it interesting or unexpected, and camaraderie. Which is why the connections she made between so-called jazz and contemporary classical, beats and electronic music, rappers and dancers, standards and the hard-core songbook, were completely organic, and always fascinating.”
On Wednesday night, as news of Ms. Branch’s death spread, about 75 of her friends and fellow musicians gathered on Valentino Pier in Red Hook, a few blocks from her apartment. As “Fly or Die Live” played through a phone propped up against a small, tinny-sounding megaphone, some in the crowd tapped out beats on drums or on the concrete, others banged tambourines and sleigh bells, and the young saxophonist Zoh Amba played melancholic funereal blasts.
From across the Red Hook Channel the distant sound of another trumpet could be heard, most likely from a mariachi band in a waterfront bar, joining the music in a phantom collaboration.
