Hi, there I've always thought that Gilmour is unlikely to be mentioned often. Hendrix or McLaughlin are by far more predictable. That's why it's especially nice to meet someone who thinks the same. Well, I am not keen on "the final conclusions", yet I think that blokes like Piter Green, Robert Fripp, Rory Gallagher, Elmo' James can't be left out.Ray Cooder neither! Alvin Lee, Ritchie Blackmore and Mick Taylor also could't half play.
