Update: I just received an email from the Hypnotic Brass Ensemble's production assistant. Here is an excerpt:
Recently, you posted on your f.mm: the tiny trumpet sessions blog about the Hypnotic Brass Ensemble. As a fellow fan of the band, I wanted to personally let you know that a feature length documentary about Hypnotic is scheduled for completion later this year. We’ve been shooting for 3 years, following them from their homes in Chicago, to the streets of New York, to stages all over the world. The film also tracks their unique upbringing on the South Side of Chicago.
We are halfway through production and want to keep you updated about the progress of the documentary. Let us know the best way to keep in touch, preferably an e-mail address.
