CC DeVille's solos were relative to the time in music history but that doesn't mean they're not shit. Hell, I could put up some shit demos, high-pass everything at 7k, and hijack a radio station so that everyone in San Antonio hears them for the next month and a half, and nail the 'recognizable by the sound' part completely - but horrible sound is horrible sound. Old 'DIY' punk and lots of black metal had shit production as an intentional statement, and you know when you're listening to stuff that tries to be kvlt BM or tr00 punk.
I'd say that one of metal's most valuable attributes is that it doesn't need to put anything on a pedestal solely for the sake of worship, like blues guitarists tend to do with SRV or BB King, or like jazz guitarists may do with Wes Montgomery or Joe Pass, or like Jet tried to do with AC/DC - the minute this is done, we're losing progress. The absence of the 'sacred' in metal is incredibly important, as so much has been built under the premise that 'hey, fucker, we can do better than that', and the least we can do is try - worst case scenario, we stick with the original, there's really not much to lose.
