There’s a cool little documentary doing the rounds at independent cinemas in London at the moment, bringing back to life a sadly lost treasure of the city’s music scene. Back in the early 1960s, Hackney’s Four Aces Club became the UK home of Jimmy Cliff, Desmond Dekker, Prince Buster, and more, even hosting Bob Marley a few times. Chrissie Hynde played there later, as did the Sex Pistols and Bob Dylan. Moving with the times, it then became a focal point for acid house raves, another of London’s legendary counter-culture gatherings. There’s a poignancy to the timing of the film’s release: the building where the club once stood is being torn down, another victim of Olympic regeneration plans.
