The first one minute and 15 seconds of “Firth of Fifth” is sheer brilliance delivered on the grand piano by Tony Banks. (And the title reminds me of that famous football result, Forfar 4 East Fife 5).
But my favourite Genesis track (and this is certainly not a political endorsement – one of them was allegedly a Maggie fan, I seem to remember – but then my favourite author is Evelyn Waugh, who was certainly no liberal) is “In the wilderness” which is well worth listening to, as it is a rather obscure album track which hardly anyone has heard of. The strings make the track, in my mind. In fact, I think there is a suggestion of a double bass in there somewhere.
Both the mentioned tracks are below on YouTube:
