My love for Genesis covers all albums up to Wind & Wuthering - Lamb, Trick and Selling England being my faves. As has been mentioned, seeing Steve Hackett live is the real deal. He usually plays a couple of classics from that period - Los Endos being a killer to end his set with. One of my biggest regrets is never having the chance to see that classic Gabriel led line up live - and there' very little quality film footage of that era either, more's the pity.
On the GR 55 front, has anyone posted any good Hackett patches here?
