Which two 50min concerts were they java master? Are there bootlegs? I'd like to check them out. You might of course be right about them ( BB&C have admitted they played badly sometimes and given their schedule and their venues who can blame them) but even if if you are it wouldn't change the fact that there is ample evidence that you would be wrong to extend that verdict to other concerts. And if there are so many other guitarists who can smoke Clapton as you say how is it that none of them have produced any really great pieces of (electric guitar) music where Cream have produced several, in a period of only 2 years where, in addition , most of there work has been lost.
It has often struck me how often people are impressed with guitarists who are just showing off and how they mistake this sort of thing for real music. It should be obvious that a preocupation with showing what a great guitarist they are is often the reason why the music itself is so unsatisfying.
There are many fast and flashy guitarists around these days, although back in 68 there were none, but most of them are technicians and circus acts not great musicians.
