It doesn't look like much from the outside. A set of wooden double doors with the small emblem of a cartoon-like submarine are the only thing that divides the Sub Club from passers-by on Glasgow's Jamaica Street.

But down the stairs, anyone who enters this cavernous basement is immediately struck by the sense of history. All the great DJs have played here, from Carl Craig and Kerri Chandler to Derrick Carter and Roy Davis Jr. When a fire destroyed the building that stands beside it, in November 1999, it was feared that Glasgow's pre-eminent underground club might be forced to close its doors for good. Seven years later the venue is celebrating its 20th birthday, a milestone that places it among the city's longest-serving dance clubs. But the Sub Club is not just an institution in its native city. Regularly ranked among the best clubs in the world, the name and the now instantly recognisable logo are icons of British clubland.

"The thing about the Sub is that it is constantly changing. New people come in and are hooked for the same reasons I was - so to every generation that is their golden era," says Sub Club current co-owner Paul Crawford. "I think the reason it has lasted so long is the DJs and people who have worked there over the years; everyone has had a passion for the place."

In 1986, Graham Wilson opened the Sub Club where it now stands with local publican Craig MacLeod. In the early days the playlist was a rotation of soul, funk and hip hop interspersed with the emerging sounds of the house era. Along with Wilson, the first DJs to play the Sub Club included Nick Peacock, Bob Jefferies and Harri, who still runs the club's flagship Saturday residency, Subculture, with Domenic Capello.

Residencies have come and gone but to date Subculture has occupied the decks for 14 years, while Optimo, where a certain Franz Ferdinand cut their teeth, has been making Monday mornings a headache for just under a decade. "My first memory of the Sub Club was getting a knock-back at the door," recalls Harri.

But he was soon let back in to launch Atlantis, the Saturday night residency that ran from 1990 to 1994. His cohorts were two still-relatively unknown young DJs called Stuart McMillan and Orde Meikle. "Then, there were lots of people wearing white 501s but over the years the club has seamlessly morphed from one era to another," says Harri.

The week-long celebrations to mark the club's first score continue tonight with a live performance from hip hop's original superstars the Sugarhill Gang, followed by a double header with Louie Vega and vocalist and New York club doyenne Barbara Tucker on Friday night. The festivities culminate on Saturday with a set from New Jersey house master Kerri Chandler. At this rate, who would dare bet against another 20 years?
