Progressive rock keyboardists are generally over-the-top, delivering lightening fast, endless solos in a variety of odd metres. Tony Banks was the exception. A founding member of Genesis, his work was tasteful and often restrained.
Whether he was whipping up a maelstrom of Mellotron to herald the Watcher of the Skies or tickling the ivories for the tinkling intro to The Lamb Lies Down (on Broadway), his playing was always in service to the song.
That isn’t to say that he couldn’t rock a solo - check out the blistering Riding the Scree, or the plaintive wailing ProSoloist licks at the end of Entangled for example - it’s just that Banks exhibited a sense of arrangement and purpose so often missing in the excesses of his peers.
