Clapton likes to see himself as a blues man, and he's certainly had the life experience, but to my ear he lacks conviction - there are far better guitarists out there. Eric Clapton has all the ingredients, but somehow they don't combine to make the whole ... in my view.
I agree with you about Beck - he's technically brilliant, but not to my taste, musically.
Last night they each did a one hour 'solo' set. Beck's was all instrumental except for one number when Joss Stone came on to do the (excellent) vocals.
Clapton's solo set was, frankly, self-indulgent. The first 20 minutes were sit-down acoustic but he picked up his Strat for the other 40 minutes or so (fantastic versions of Cocaine and Crossroads).
However when they came together for a final one hour set it was more like a 'battle of the guitars'. Neither of them looked at each other once throughout the set. It was as if they were in their own little 'bubbles' playing for their own enjoyment.
I love Santana and his impossibly-long held notes. His band was fantastic when I saw them a couple of years before this clip, during his Caravanserai tour... stunning! I suspect, hearing the organ (Greg Rierson?) and percussion, it's the same band.
Clapton is astounding, but can get over-indulgent, as CIG noted (it must have have hurt to say that lol). I saw him on TV over Christmas with Andy Fairweather-Low and the show was amazing, with two great guitarists showing respect for each other.
