I agree with most of the above but, at the risk of being controvertial, I often think that blues purists (myself included) are too quick to dismiss bluesmen and wimmen who ain't dead yet! To illustrate the point, I once saw (live) Prince, as he was then, play a guitar solo which made the hairs curl and the ladies swoon like only a true blues genius could. I only use the purple one as an example but does anyone else turn on a CD by a band you wouldn't expect it from and find themselves living a totally blue moment?
