Sorry--Hiney, but I know what tracks James is on and my opinion hasn't changed. Perhaps he is "great", but to compare his playing to Eddie Van Halen in style or anything else is..well..just daft. And young James hasn't shown this greatness on record yet--maybe he is and maybe he will one day.
Well, I am not at all familiar with Van Halen, so I can't say anything on the subject. But I do agree with your comment that there is no evidence of greatness in Mac Jr. He may have some talent, he may not. We'll have to wait and see.
The difference between genius and insanity is merely the difference between success and failure.
