I view Floyd as a band that produced the most awesome lyrics and musically I regard them as a guitar band.

David Gilmour has a "sound", one can identify him in anything he does.

To me, the keyboard and drum parts in Floyd could have been played by any competent musician. What I mean is that Richard and Nick don't seem to have their own style/sound.

I'm not denying their contribution to the band but just wonder if their importance is not being overstated here.
