I have long considered Tony Banks the key creative force in Genesis, and the man behind some of the most memorable elements of the classic 'prog rock' albums of (gulp) 30 years ago like Foxtrot, Nursery Cryme, and Selling England by the Pound - which by the way still sound pretty good if you like that sort of thing.
With 'Seven', he demonstrates the full range of his melodic gifts and abilities as an arranger. I don't know how the classical 'establishment' would take to this stuff, but if you like (for example) Elgar's Enigma variations, then chances are you would enjoy Seven. I was slightly surprised that that the keyboard elements are so low key, given his background, with the major themese being delivered by strings and woodwind (plus some brass), but the music is none the worse for that. If I had to make a criticism, it is that the seven pieces, while sharing a common style, lack any real unifying or repeating themes, and come across as a collection of separate works - which is, I believe, how they were written. Otherwise a real treat, and very reasonable priced into the bargain.
