Trumpeter Jamie Breiwick is a tireless promoter of jazz in Milwaukee. He is also a prolific performer, too. On top of that, he releases recordings - as a leader, as a sideman and with his group Choirfight - at a pace that recalls the golden age of jazz record labels. His latest disc is called "Spirits" and was recorded, like many of his works, at the Jazz Estate on Murray Avenue, back in November.
