There are few big name lead guitarists (Dave Gilmore, who has the best sense out there of "The Long Line", is the only one that comes to mind) that I like more than Clapton. But Russel's/ Harrison's presentation works better for me, for several reasons. The open sounds in Russel's / Harrison's presentation are meant to indicate spacing out across the void (as indeed, Russel and Harrison undoubtedly were, Lysergiata being the custom of the day) ... and then, as like dropping back into the earth zone, Russel lands abruptly on that hard minor chord in the bass. Russel's voice is far more polished, in the sense of transmitting nuance, as well.
One of my favorite Clapton covers is his rendition of Dylan's "Sign Language" .... but I'm getting even off topic-ker here.
Well, added later: Came across a version of "Beware of Darkness" by a group called "Spock's Beard" .... And as you all know, Spock is or was a favorite Sci-Fi character of Tom's. They sound very zingo-techno in a retro way, very much like the old band called "Yes" ... very clean and precise music.http://www.youtube.com/watch?v=jGd6gUSTMDs
