Texas-born rock icon Janis Joplin has been one of American culture’s most compelling figures for more than 50 years, in large part because of the intrigue she presents: Just who was this storm of a singer, and just what inside her came out as that voice? In Janis: Her Life and Music, author and music journalist Holly George-Warren makes a definitive exploration of those questions, laying out in impressive detail the particular personal alchemy that led Joplin to forge all-new alloys of power and vulnerability, freedom and fatalism.

Enabled by dozens of interviews and access to key archives, including the Joplin family’s, George-Warren achieves the assured voice of a biographer who knows her subject as well as anyone can. She chronicles every verifiable event and significant relationship in Joplin’s life so thoroughly, and quotes Joplin so thoughtfully, that when occasionally she allows herself a bit of speculation—Joplin “must have” or “might have”—it feels earned and insightful. And when the story reaches its sad end, George-Warren’s previous explanations of why Joplin used drugs—alcohol since her teen years, later speed, and by the end heroin—make the singer’s overdose death at 27 seem almost inevitable.
