Heavy Music Mothers: Extreme Identities, Narrative Disruptions is an exploration of women and heavy music and the ways in which women have historically engaged with musicking as mothers. Julie Turley and Joan Jocson-Singh, musicking mothers themselves, largely employ an ethnographic lens, foregrounded in powerful one-on-one original interviews as vignettes that narrate thematic patterns. Other chapters examine motherhood identity embedded in respective published rock music memoirs, discussions of rock performance as a site of maternal bonding, and themes that arise when heavy music mothers write about motherhood. Autoethnographic portions throughout give the book an intimate and personal tone: one such chapter presents the concept of vigilante motherhood within an auto-ethnographic context. The authors reference the book's limitations, meditating on historically marginalized moms the authors predict and hope the focus will be on for the future. Heavy Music Mothers is a robust study of women and motherhood set within a music culture historically inhospitable to both women and mothers. This book, the first scholarly study of this topic, is just the beginning.
