It is a big rectangular shaped stage with little wings (kinda like a fat 'H') that the guys could walkout onto, Lars had his drumkit on a rotating platform, which was moved at different times through the show, and the other guys walked around the stage freely, playing to all angles of the crowd. There was a 'mosh pit' area on the floor of the tennis court, the rest of the arena seating was used the lower section 'gold' tickets the upper 'silver'.  All the speakers hung from the an over head frame the 4 legs of which were very thin so basically no matter where you were you had a great view.
