Info from Wikipedia
Riverside was a music venue in Newcastle upon Tyne, England which operated from 1985 to 1999.
The Riverside name has been resurrected for a medium-sized music venue and nightlife spot in the city today, although it is not a direct continuation of the original venue.
The venue continued to trade until the building was sold in 1999. Foundation nightclub then ran on the same site, from 2000-2005. The building is now office space with a private gym where the venue once was.
