Howlin' Wolf is a legendary figure in blues music, with an influence that has seeped into the pantheon of rock 'n' roll via influential figures namechecking him, such as Keith Richards. His life story is presented here, tracing his career back to its roots, and following his battle against hardship as he strove to get his music across to a wider audience. Unfortunately this only occurred posthumously, but luckily director Don McGlynn has exhumed a welter of material from the vaults, much of which has never previously been made public. Discover a blues original for yourself with this fascinating, in-depth documentary.
