I don't know why he did it. Maybe he played some Freestyle for warming up and then started his planned Early Hardcore set...
I see why he cut this bit out. It's mainly (but not all) Dance Ecstasy/Acardipane/Cold Rush Records (all German) or related releases. 'La Cosa Nostra - Full Of Shit' one of the best tracks here (USA) release at 01:00:45 and Brainkiller on F%@#ing Loud! (German label) just before that track.
