I think the band needs an outside ear. I have said that ever since Scenes. I don't agree with every move they made on FII (outside writers, for me, are a no-no), but some of the decisions (such as lifting out Hell's Kitchen and making it its own song) were great ones.
To me, FII was the most successful DT album where their core sound and progressive nature were captured, but at the same time, crossed over more to the general metal and hard rock fan. Sure, with I&W and Awake, DT was arguably more popular, but FII was more (IMO) accessible than either of those albums and was a great balance.
But once MP threw his hissy fit and got his way, while many fans loved what came next, I felt the opposite.
It is true, that at least from a wide perspective, it was the right choice for the band. They got Jordan, focused on their virtuoso-type playing, etc., etc. They got mountains of new fans while many other bands crashed and burned (case in point, my favorite, the ORIGINAL lineup of Queensryche, who experimented TOO far in 1997 and obviously, after Degarmo split, haven't really been the same since -- but that's a different story).
But to me, DT lost the plot in that their songs were getting long for the sake of being long. A GOOD PRODUCER recognizes a band's talent, it's expectations, but also focuses on the core elements of "what makes up a good song." They are able to look at something objectively and make suggestions to refine things.
JP, as much as I love the guy, is not the right producer for Dream Theater. He's the primary songwriter. I know there is a history of great songwriters that self-produce their bands' releases. Steven Wilson comes to mind immediately.
But to me, decisions need to be made to make changes to songs to make the song BETTER. Much of that could start by taking out elements that while cool, don't enhance the overall vibe or mood of the song. Not stripping it away, not talking about eliminating solos. But looking at song, cutting a bit there, suggesting a different approach to a solo here, etc., etc.
Dream Theater is missing that. ADToE is missing that.
And I know that opinion is not popular. And that's ok, because opinions are like assholes. Mine stinks after a shit as does yours.
But yeah, I think DT is in bad need of allowing someone they trust, but perhaps don't always agree with, come in, and really PRODUCE an album with them, and let it roll and see what happens. I don't want DT to be a mainstream hard rock band. But I also think their songs need to be refined...which is something a good producer does.
