No, a lot of the music they play was never even released on vinyl. But they do dig up very weird tracks, so there is some sense of discovery that record collectors have in always trying to find new sounds. As long as the record has the right sound, they will play it. For example, there is a track off the Vanilla Ice movie soundtrack "Cool as Ice" -- I don't know who discovered the track, but it's obviously a rare soundtrack. There isn't a focus on the DJ having originals though, more on the DJ actually doing a good set. Older people (usually 35 years and older, including many people in their 70s) dress up really nice and do sort of complicated steppers dances.
