No, not the pundit--the guitarist. Over at Blogcritics, Michael J. West writes:

It’s for that reason that I suggest (not propose, but suggest; this one needs far more examination before it can really be a solid theory) that John McLaughlin is the real key figure of jazz fusion. He and Miles stand toe-to-toe in that sub-genre's pantheon: Miles, the man with the vision, and McLaughlin, the only one who knows how to execute it.

Since the death of Segovia, I think you could easily make the case that McLaughlin is the world's greatest living guitarist, in terms of both breathtaking technique and all of the musical genres he's dared to survey. But I'd argue (and in fact already did so back in 2003) that McLaughlin's greatest moment with Miles Davis wasn't the much more celebrated Bitches Brew, but the next album the two men would record together, the blazing (and most definitely rocking) A Tribute To Jack Johnson.

(For McLaughlin in a much more tranquil vein, check out the above clip from the mid-1980s with his then wife, pianist Katia Labeque, which I've been looking for an excuse to post for a while now.)
