Saw Röyksopp at Southside in 2004. They played a pretty good set on the small stage; didn't get too far away from the "Melody A.M." material (which is one of the best albums of the past few years) but they seemed a bit nervous or stiff at the beginning (programming problems could not have helped their mood).
I guess they are touring to support their new album "The Understanding"... which sadly hasn't received the best reviews.
