[1] Although Sterns had played such music before and was a forerunner in underground parties, the most famous club nights were started in 1991 by a promoter named In-ter-dance run by the late Mensa.

The Underground was located at the lowest level of the building partially embedded in the hillside in a large concrete bunker.

On the second set of steps the bass was so intense it was difficult to carry out a conversation with someone adjacent to you and for them to hear you without speaking right into their ear.

This had car hub caps on the walls and the DJ's decks were located in the front end of a VW Beetle which had been chopped in half.

The sheer range and variety of DJs and performers that have graced Sterns is testament to its place in Rave and Hardcore folklore.

There was a very large range of flyers produced and often they parodied well-known brands or popular culture of the time, such as Holsten Brewery, Swan Vestas, Marmite, Benson & Hedges, Perrier mineral water and the Blockbusters quiz game show with its tag line "I'd like an E please Bob!".

In late 1990, through a chance meeting, at Chaffinches Farm, Birdham, West Sussex ("The Farm" was the home of In-ter-dance, in the early days), between "Jamie 2K" & Mensa, a deal was struck to produce a new format two Colour Members Newsletter, shortly after this Jamie 2K started to print the In-ter-dance Flyer's, through his then company Power Leaflets/ renamed in 2013 to Get Fruity) .

This flyer and all the material used to produce it had to be destroyed; as the brand owner of Holsten threatened court action if their request was not complied with.
