John Mayall has passed away

I was never deeply into his catalog, but the live Jazz Blues Fusion disc is not only a favorite, but it is one of the best recorded discs that I own live or studio. Great music and great players

It’s a good one. One of my favorite Mayall recordings from a guitar standpoint. F. Robinson’s jazzy approach is such a refreshing change from the Blues Rock approach... not that I don’t like that, as well. But his playing is, IMHO, a major contributor to the overall vibe of the record.  

Clapton's playing on that album is indeed some of the best of his career. I can't say it's my favorite. Forced to choose just one album, I'd pick Layla, mostly because I prefer its more melodically and harmonically sophisticated song structures, but for straight Blues played by Brits, Beano is about as good as it gets. I love P. Green's playing with F. Mac but I can't honestly say it's better.

Thanks. I'm familiar with both of those. 

I actually prefer the live Boston set to the other you mention. 

With both, I skip the J. Spencer stuff. 

The playing on the 70th anniversary set was better than I'd anticipated.
