Guy, were you actually at Stafan Grossman's workshops? I vaguely knew him 30 years ago, but must admit I thought his playing was a bit suspect. He seemed to be playing at the limit of his ability, or just beyond, with the tempo running away with him at the most difficult bits. It's not a feeling I ever had about most of those who turned up in the best-guitarist-ever threads - but I know some pople who put Stefan up there with the all-time greats.
