I became a fan in 2006 and right after they had stopped doing "evening with" shows, so for a long time, that's all I wanted to see. Eventually they returned to doing them and I was ecstatic. But over time, I kind of felt like they started milking it. No rotating set lists, shorter and shorter sets (they still do a longer than normal headline set, but not the longer ones they used to do). Once the spontaneity was removed and I saw most of the same songs over and over again (yes, DT does a great job rotating songs, but after ~20 shows, you've seen many repeats) I started thinking I'd rather them bring out a younger band that the audience may like and also may draw new fans to DT to keep things fresh. I'm pretty happy about this decision. I think it's best for both DT and the opener. Also to add, when DT would hit the stage, it was usually not to a huge crowd as people would still be getting in and also not really be ready for the music just yet. An opener bridges that gap, loosening the crowd up. We will still get a DT headlining show. Maybe the bands collab on something as the tour goes on. I miss seeing things like Dweezil Zappa playing Metropolis with DT for a special appearance at the NYC show as he was the opener and it allowed them to have a cool moment together.
