WHAT IS IT? Up to 50 percent off tickets to a dramatic, fascinating look at London after dark. WHY BUY? With over 200 works from more than 60 photographers, covering late nineteenth-century London to the capital as it is today, this fascinating exhibition at the Museum of London captures a unique look into the city’s nightlife. Curated by Anna Sparham, contributors include Alvin Langdon, Bill Brandt, Rut Blees Luxemburg, Tish Murtha and Nick Turpin. Their collection of images span more than 100 years, capturing the smog-filled Embankment of the 1890s, ‘40s street workers and buildings bombed during the Blitz through to reggae fans from the ‘70s and more modern photos of the booming grime scene. It's an engrossing exploration into what our reviewer called ‘London’s nocturnal alter ego’. Plus, the exhibition is open late every Friday evening – how fitting! Well worth a see.
