Following the interesting discussion in this thread about Banks's keyboard sounds on WCD, I started thinking more broadly of his moments I particularly like in the work of Genesis and would like to hear members' own thoughts.
Chords are of course a major element of the Banks/Genesis sound, and this applies to a part that was key in making me a fan, namely the huge Hammond chords under the "now, now, now" at the end of Musical Box. That, and the way the Hammond builds from just after "...your flesh", sounding almost church-like then swelling to the big ringing chords during and after the vocal part. I remember being very struck by that whole end section when I first heard the song around the mid 1970s (along with Apocalypse I think it's one of the best segments they did), but those chords especially really stood out. I was saddened that the 08 remaster seemed to diminish them somewhat.
Speaking of Apocalypse, the chord sequence during that is absolutely immense. I also love the quiet entry of the choir after "...don't give a damn" in Moonlit Knight and how it then gloriously swells. The choir in the latter part of Entangled is lovely, like being in a warm bath of sound. It's an effect he wisely used quite sparingly and always made it count. He could have drowned Silent Sorrow with it, but kept it to a minimum, leaving the majority of the track as the bare-bones six-note motif with some overlays but still somehow ringing after the gorgeous wash of choir. Newer prog bands often overuse it to a ludicrous extent and sap its power. The Watcher opening is another obvious mellotron high point.
Focusing more on solos and lead lines, the Raven solo will always be a favourite of mine, specifically the original. But while he's an accomplished and usually interesting soloist I'm often drawn more to the little touches and fills he's so adept at, eg that tiny little bridge in NYC after the "off we go" section before it returns to the main verses. The bright 6-note theme in the chorus of Silver Rainbow, in BTL the 4-note piano fill after "I will help you" (under the ooh-ooh-ooh-oooooh), the lead line in the chorus of No Son, all bits I love.
