With an ear for the overlooked, Aaron Gilbreath chronicles the forgotten corners of the mid-century jazz scene. Shadowing the greats from Sonny Clark to John Coltrane, Gilbreath traces the tragedy of saxophonist Hank Mobley, unearths the story of self-exiled pianist Jutta Hipp, and pauses on the meaning of heroin for trumpeter Lee Morgan. He also revisits a few standards, like The Connection, an influential film with its own take on drugs and sobriety; the ten-year evolution of Miles Davis' "So What"; and the impact of record labels' vault archives. This Is: Essays on Jazz celebrates the joy, genius and struggle of jazz, in essays both intimate and deeply researched.
