Just look at this thread as an example too. MP clearly gets the conversation started.
I suppose, if you believe that "any press is good press".
Why do you assume this stuff is "bad", or that it should be "bad"? I'm not here AT ALL if not for Mike Portnoy (no jokes, please).
I got into DT back in '92 with the first album. I was already moving on from metal to prog, and it wasn't really my wheelhouse, but as I learned more about the band - local to me (they played absolute DUMPS in Connecticut for many years) - I realized they were something special. It wasn't JUST about the music, it was about the community, almost like the Dead. What you call "tacky" - and I understand why you say that - is part of the charm for me. They were bold, proud, and trying to do something different, and as a fan that was just as obsessive about the bands I like, it RESONATED.
I like a lot of bands. My top 20 or so is almost interchangeable. I have 2500 CDs in the next room. I CONSUME music. So it takes something to set a band apart. Sure, bands like Genesis, Maiden, Kiss, Sabbath, Beatles, Zeppelin are special to me, but Dream Theater is something more.
Everything I like about those bands, DT takes to a different level. And I'm sorry, no knock on Mike Mangini, phenomenal drummer and all around great guy, but when Portnoy left, they went from "God-tier" to "one of many really awesome bands". I can safely say that other than a complete fluke, I will NEVER get to meet any of Genesis. Or Sabbath. Or The Beatles (even MIKE was thrilled to have met Sir Paul). Even Maiden are not really fan-friendly in that way. Mike? I've met him several times. They are very accessible. Granted it's not always gone well, but there's actually a chance you can X or whatever a message to Mike and he will answer. I have an experience I can't really share the details on, but they - the organization - KNOWS we exist and more or less CARES about us. I was on the Genesis forum and the Phil Collins forum for a while and Phil made like one post, it was HIGHLY defensive and negative, and it was like "why bother"? These other bands dabble, and DT delivered.
Mike's a completist. Kiss box set? Chock full of rarities, but "one of two songs" recorded by, or "one of three songs" from the demo. Genesis archive sets? Three songs missing because the band "didn't like them anymore". Mike puts BOTH songs recorded by, ALL the songs from the demo, and a complete set. Even DT without Mike... releases half a show on one disk (no encore) and the other half on another disk (no encore) and... there's no mention of said encore. He would have at LEAST said why it wasn't released. On one of the Flying Colors live disks, there was a line in the liner notes about an impromptu jam of "Space Truckin'" by Deep Purple. Bummer that it wasn't in the track list, but sunovabitch if on the Blu-ray there wasn't a hidden file of.... the Space Truckin' jam. HE GETS IT.
Look, if these things don't matter to you I understand. But for some of us they do and they need to be factored in when judging things that happened in some cases 20 or more years ago.
