reb beach is easily 1 of the top guys who defined hard rock or "hair metal" back in the glorious 80s, alongside guys such as evh, vito bratta, richie sambora, ritchie kotzen, blues saraceno (though i certainly think he is much more than just a hard rocker), george lynch, mick mars, cc deville etc etc .
can you say kirk hammett is 1 of the top guys of metal? nope. that credit goes to guys like james hetfield, chuck schuldiner, trey azagthoth etc etc..
reb's comment about hammett's guitar playing is spot on. with reb's calibre, it's certainly a credible comment.
