It's been a while since the MSI album and concert, so my memory may have dulled, but I feel safe saying that it sounded nothing like Jimmy Urine solo.
That's not too surprising; there was never any reason to think that MSI's sound would be the only or truest expression of any of its members. It does make listening to The Secret Cinematic Sounds of Jimmy Urine pretty fascinating.
There is a strong '80s influence, with some of the songs having been written long ago. One review mentioned that "Salome" could go right on to the Heathers soundtrack, but I say "Not For Me" sounds like the middle of a John Hughes film, when everyone is getting all broody on their way to the actions that will shake them out of their respective funks and bring on the upbeat music.
I particularly loved "Patty Hearst" and "Fighting With The Melody" - for different reasons - but I have to give special attention to "All Together Friends Forever". It sounds like the theme song of a children's show, but the kids in the audience are children of the corn or something. Maybe you can't put your finger on why it's creepy, but it is creepy, and that lack of definition makes it more unsettling.
(There is an associated short film. I'm sure it would give one explanation for the creepiness, I'm not sure I want the mystery solved.)
All of this leaves me really wishing for artist commentary: what inspired each track? What does it mean to you? What movies or video games would they go to? I believe Jimmy would give answers that were interesting, insightful, and fabulously odd.
That is why I was looking at other reviews. I usually don't, but I was left wanting to know more. I didn't find much, so that just leaves me with listening and extrapolation.
It could be worse.
