James: Impossible to choose. Off the top of my head...the ending scream of Intervals on Score.
JP: TBOT solo
JM: It's a super small thing, but the bass fill in the quiet section of ITPOE, right after "Angels fall, all for you, heretic..." is so perfect. The Metropolis solo is right behind it.
JR: This one is tough. A lot of candidates, but the first BTL solo is one I always remember as a big moment. Most of his piano, continuum and Zen Riffer moments are contenders here.
MP: Finally Free ending, LSFNY
MM: The big fill down the kit in TSF on BTFW, leading into the Repentance section
Sherinian: Good piano work in Anna Lee, I guess?
Moore: The last keyboard solo in LTL
Dominici: Chorus of Afterlife, I suppose.
Collins: The gift we bring Your Majesty, YAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!
