For the eight young men in the Hypnotic Brass Ensemble, “brotherhood” is literal: they’re all sons of anti-establishment jazz legend, Phil Cohran. They grew up in the same house, in a family of 24 siblings. Cohran and their mothers raised them together on Chicago’s tough South Side on a strict diet of jazz, funk and Black Consciousness. Family band practice began at 6 AM. Now grown, as they raise eight brass horns to the sky— whether playing their unique blend of jazz, hip-hop, and soul in the streets of New York City, collaborating with Mos Def, or negotiating with record labels— they find the values their father bred into them constantly tested. They struggle to decide whether his principles really are their own.
