I only went there a few times so cannot give you anything in depth but many years and clubbers who flocked from far and wide descended on the city to experience Sheffield at its clubbing peak over a decade ago, clubs like The Republic, Niche, The Unit, Insomniacz, Bed, Embrace, Club XS, Club Wow were all going toe to toe at some point and Sheffield it seemed was the centre of the universe as far as dance music was concerned, now it's all pretty much dead.
