I'll have to admit, Chili, at first glance, your initial remark seems to say that you decided to stop liking his playing, which you'd previously enjoyed, because and only because he said he wasn't into the blues in the same way that you are. If that's really what you meant, then so be it.
I suspect gerald was saying that LB could have "lied" and said the blues were his main thing and he loved it knowing that that would give him a certain amount of instant cred with some guitarists. But it isn't, so he didn't. It's just not his true love playing-style-wise.
