Bar Matrix was once a staple of nights out in Sheffield city centre during the noughties.
The bar on Charter Square, at the back of Debenhams, later became rebranded as another nightspot called Nylon. The area has been completely revamped now in the Heart of the City project.
We pulled together this retro gallery of pictures taken at the Matrix. Can you spot any familiar faces?
