Okay, I have to say, great idea for a thread.
MP: SC - I just feel like he really allowed himself to let loose on it. It's similar to ToT, but in this one, if you listen to his parts, especially on ITPOE, he really does some cool stuff there. And hey, he also did some vocals on the album that actually sounded kind of cool. His back and forth rap in Constant Motion was fun, and his little rap on POW is pretty cool too.
JLB: Awake - I'm not the biggest fan of Awake, but as a vocalist, I have a hell of a lot of appreciation for it. It's got a couple of songs that are pretty good, and then James starts singing and turns them into amazing rockers.
JR: SFAM - It's interesting that they kept MM out of ATDOE writing sessions, because clearly, putting their newest member (at the time) into the SFAM writing sessions really paid off. Jordan contributed so much awesomeness to SFAM that I can't even describe it. He turned what they originally had for Metropolis Pt. 2, and made it into sweet, sweet candy. As well as conducting the choir in TSCO.
JP: SC - Like it or not, Systematic Chaos had a ton of Metal elements in it, and really allowed JP to shine not just in terms of badass riffs like on CM and TDEN, but also more melodic, NWOBHM and Symphonic Metal inspired riffs like in ITPOE and Forsaken.
JM: I&W - To be honest, I'm not the first person to spot a bass line, I really have to listen carefully to pick it out in a piece of music. But maybe it's because of the way it was mixed, I&W really shined with the Metropolis bass solo, as well as the parts on Learning To Live.
KM: I&W - Kevin Moore did some interesting things on Awake, but personally, I think he was always best at just composing and playing beautiful melodies. And while Awake had SDV, I&W had Wait For Sleep AND Surrounded AND Metropolis, and pretty much every song with some great, beautiful melodic keyboard parts to it.
