Being in a successful band sounds like a dream lifestyle in many ways, travelling the world entertaining your masses of fans, but then... there can always be too much of a good thing, as we learned when Zayn left One Direction recently. Or when Robbie left Take That... or John Lennon leaving The Beatles... the list goes on. This documentary sees Mark Radcliffe look at the highs and lows of life in the music industry, focusing on the creative tension that produces great material (Fleetwood Mac being the obvious example here) as well as the pressures that come with success and fame that can pull groups apart. He examines the most common reasons bands split up, as well as the secrets of those that managed to stay together.
