Combining music, spoken word, and visuals, London-based trio Public Service Broadcasting play upbeat post-rock which sources the majority of its vocals from public service announcements, documentaries, and other archival material. With a mission to "teach the lessons of the past through the music of the future," the group's music is heavily based on historical themes. 2015's The Race for Space focuses on outer space explorations from the '50s to the '70s, while 2017's Every Valley is about the rise and decline of the Welsh coal mining industry.
