I'll check back in there joe. Looking forward to your take on it.
I'll try to be short and concise on this though I'll probably wander and get muddled, which is nothing new.
First of all I'm not going into the concepts of metal as I think you'll probably know all about that.
In regards to me throwing KC into proto-metal, let me say first of all it is on the borderline and I have to admit that there is fanboyism involved here as well.
There is the fusion of mutated classical and jazz elements consistent to metal in many of King Crimson songs that though the blues based formula is almost non-existent which isn't the case for most of the proto-metal bands, especially in the early developement ('67-'72 as alot of the bands started to shed thier blues/psych influences) as well KC also implements the tritone in many of thier songs, "Larks' Tongue in Aspic" as one example. Also, alot of Fripps lyricism incorporates nihilism, doom, sci-fi and dark subjects and even the occult. Fripp does lay down some very technical, metallic power chords in unison with stabbing time sig shifts that IMO did influence alot of artists but didn't have the immediate impact and infuences in that time of the early/mid 70's as other protos like Sabbath and Zeppelin but would be influential in latter years but not so much on metal artists though some bands cite KC as an influence, Iron Maiden, Voivod, Tool, DT with a few others.
Now if there was a proto-prog metal sub-genre, I wouldn't haven't any reservations dropping KC in there as I would throw in Atomic Rooster and Night Sun. .
Really, I'd prefer not to have any sub-genre with proto in front of it.
No question, not all of KC's albums from the time period of '69-'74 are what I would place in proto though I'd throw in ITCOTKC, Larks' and Red. Now, does one song off one album that I or some consider to be proto constitute that album to be proto. Again, that comes down to one's own opinion and criteria and for me an artists that has one or two proto tracks on only one album and/or within that artists discography doesn't necassary classify them in proto as other factors come into play like how much influence that particular band/tracks had on future artists. Tucky Buzzard comes to mind as IMO had only a couple of proto tracks on one of thier albums and how many bands did they have an influence on(?). Not too many I'd think.
TBH, I really don't have a problem with others including Dick Dale or the Kinks in
thier own proto-metal list as I can appreciate thier contributions to metal but my criteria is the parameters from 1967-1975. Some may go back further and by all means.
I place LZ in proto but not in metal as I place Sabbath in both and don't consider an artist from some far away land like Brazil or in eastern Europe behind the iron curtain with one album with a few tracks or a couple of singles that could well be considered proto as I doubt they had very much impact and influence though they might of in thier immediate region.
I find it easier tagging many of these bands of proto with other labels such as metal, hard rock, heavy psych, heavy prog and Krautrock as that's what I have done for so long as this proto-metal sub-genre, from what I gather is a fairly new and TBH hadn't heard of it until Wolf's Proto thread, though I do understand what the purpose of this sub-genre is about...for the most part...I think.
I could go on...and I'm not about to argue with mine or anybody elses list. I'm out.
