It is a very insightful view into the history of disco music through vintage photographs, home videos, and a wealth of new highlights including artefacts not previously displayed in the UK. It took me around 90 minutes to go through all descriptions, videos but I did not manage to listen to all audio tracks and watch all videos in full. If you are a super fan, you will certainly be spending half day there.
I particularly loved seeing the famous disco outfits. I wish there had been more on display.
Ideally you should visit the exhibition and then go straight to the Mamma Mia! The Party which is located next door to this exhibition.
