I have to say something that may be unpopular, but with respect to James LaBrie solo work...
I love the guy's singing. He (and Mike P.) were the reason I got into Dream Theater back in '92 when I first heard Pull Me Under and went and bought the album. His vocals just blew me away. LOVED them, and for the most part, still do.
So you'd think I'd love his solo stuff, right? But I have Elements of Persuasion (which is pretty good) and Impermanent Resonance (which is just not clicking). I'm sort of lost; I just don't get the point of his solo works. He's not the primary writer (though it says he wrote most of the lyrics from EoP), so he's singing someone else's works again. I can't stand the screaming vocals - he's a singer, so I'd rather hear HIM sing than the drummer - and the music sounds like any of a 100 bands from 2004 looking to make it in metal (Linkin Park, Three Days Grace, looking right at you). That over-compressed, over-processed metal sound... I would have been interested to hear him take on a different genre, or share his thoughts, or show his rudimentary guitar skills. Something, anything, that made it HIS. Just seems so... pointless to me.
