The world's best blues guitarist? Compare and contrast.

I was in the car with Maureen and Ian and there was some brain loosening blues guitar playing on their car stereo. (Not the car stereo that went underwater in the great Wadi Sinking of 2008). I asked who it was and that's how I was introduced to the incredible Joe Bonamassa. Thanks for the intro Ian. If you like blues in the style of Led Zep's "Since I've been loving you" or if you like Robin Trower or Gary Moore with a touch of Kenny Wayne Shepherd then Joe Bonamassa is the man for you . He's a blues guitarist and singer from the US who's amazing and I can't understand why he's not better known. (He was a child prodigy and was only 12 years old when he first played with BB King.) His producer works with Joe Satriani, and Bonamassa has also worked with Leslie West so if those two gents are involved then that's it for me anyway, all the boxes are ticked and I'm hooked.
