I prefer the Twisted Logic-Tour Era. Maybe because X&Y is my favourite album, but I like this setlist more than the current.
But furthermore, I agree with Fitz aswell. Today, a Coldplay gig is a show. A real one which entertains. But back in 2003, they came on stage and just played. There where some lights, that's it. In 2005/2006, they had both, parts of the AROBTTH-Era which focused the music and parts of the VLV-Tour which focused the show. And that's exactly what I think defines a great band.
