Hi. I'm still getting into progressive rock, but I was first introduced to it while watching FUNimation's dub of Dragon Ball Z - The History of Trunks. They ended up using music by Dream Theater in the special, so that was my first taste of prog rock.
I've also been influenced a lot by Motoi Sakuraba, a video game composer. He was formerly part of a progressive rock band, but then started composing for games. He implements a lot of progressive rock into Star Ocean: Till the End of Time, and Resonance of Fate. He also performs his compositions live occasionally.
He is the keyboardist.
Anyway, nice to meet whoever replies to this.
