One of the most appealing of the songs by Woolly Wolstenholme, the band's keyboard player until he left in 1979, and who sadly committed suicide on 13 December 2010.
Woolly's songs, the best-known of which are examples of the often grandiose style which has since become known as "symphonic prog", always stood out from those of his band-mates for their harmonic interest and textural subtlety.
Subtle harmonic and textural touches lift this well above the ordinarily beautiful. It's varied and lasts nearly 6 minutes, building gradually, and keeps getting better until just before the end. You can tell at times that he's listened to "Ripples" and some of the good bits on "Wind and Wuthering", but this has its own space. The vocal is by a former Genesis roadie.
