they had it since they first started on the air I think... or for as long as I can remember. They got level 1,2,,3,4,5 on saturday nights..... usually level 5 is the best they get like Vicious, Boris, Hex Hector, Tsettos, Oakenfold...and some others. sometimes they got those guys on level 4 also. There all usually pre-recorded. Vicious went last week into the studio. I even called up and he picked up. So I guess the DJs sometimes stop by.
