This document provides an outline and introduction to a research project on the British Musicians' Union from 2012-2016. It discusses the brief history of the union, issues facing musicians as workers, and key challenges from changes in labor markets, technology and law. These included threats to live music work and the union's varying approaches to the rise of film, radio, recording and changes in copyright law. The conclusion questions the focus on 1955 as a watershed, suggesting conditions for rock music predated this.
