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 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 funk in the streets of New York City, collaborating with Mos Def, or wowing a music festival— they find the values their father bred into them constantly tested. They struggle to decide whether his principles really are their own.
