7She's at the Controls gives a socio-historical examination of the roles of women studio professionals in the UK music industry based on interviews conducted over six years with 30 female studio practitioners at different stages of their careers and working in different genres of popular music including reggae, hip hop and pop. The edited interviews are preceded by an in-depth exploration of the often unseen and unacknowledged gender rules of music industry practice (both personal and technical) that underpin popular music etiquette. A range of supporting material from academic works to technical publications and popular music journalism is used to expand and critique the discourse.
