It disappeared in 1969 and later the building belonged to the Czechoslovak Socialist Youth Union, which established here Klub mladých in the early 1970s.

The club's narrow and also long concert hall had a capacity of about 50 people, there was a bar, tables with chairs near the pillars and a dance floor.

The club was a rehearsal and concert hall for musicians, works of art were exhibited here by artists banned by the socialist regime, a carnival was held here every year and there was a notice board with upcoming events.

During Raždík's leadership, the Atlas klub served mainly for discos of regional disc jockeys, such as Ladislav "Laco" Gavorník, Milan Ides, and Dušan Dobrovoda.

Except for mandatory participation at the Labour Day annual celebrations on the stage in front of the Hotel Grand on Leningrad Square (Slovak: Leningradské námestie, current Town Hall Square), the club was not politically involved at all.
