Excellent comments, Learsfool; although it may seem otherwise, we have no substantive disagreement. This seeming dichotomy is further highlighted by a couple of interesting things that inadvertently go to the core of the issue. I am literally of two minds about all this, and that is the reason why I think it can be fairly said that we have no disagreement. Being someone who is steeped in the more traditional aspects of being a musician, I admit to an inner conflict concerning my reaction to the non-traditional; in this case, the avant-garde (in general, not just music). That's one mind. The other mind has (slowly) moved away from what at times was (and still is) an unnecessarily rigid view of art to a more accepting attitude that takes into account a changing world with changing attitudes and norms, and a changing view of what is "substance". That changing view of what substance is causes the most conflict for me. Not meaning to digress too much, but please bear with me:
Rap music. I WANT to hate rap. It violates so much of what I have spent so many years studying, respecting, learning and trying to hone. Yet, how does one completely dismiss a movement in music (?) that has had such a huge impact. I seriously dislike it and don't respect it. But, I don't hate it because it had to be; it reflects our culture. We can hate our culture (and in some ways I do) and we can decry the decline of standards in our culture (and art) 'till we are blue in the face, but it won't change the direction of the art (?) that reflects it. Worst of all, we can be so rapped :-) up in hating it that we may miss those rare moments when I do find myself saying: "oh, ok, I get it". How good a job it does of reflecting the culture is what defines its quality; its level of substance. Interestingly, and on a personal note, it has been my twenty year old son, a gifted young film maker and a true artist, who has shown me the value of not so readily dismissing what may not conform to MY standards. I am not talking about an abandonment of standards, but simply being more accepting of a different view of standards. I really believe that is the respect for traditional standards combined with an open mind for the new that creates the healthiest environment for really great art to happen.
The avante-guard in the arts (and I did not mean to suggest that rap is part of the avante-guard) seeks to break-down traditional standards and within this break-down a new set of standards takes shape that define it's "substance". That is not to say that one has to take on a "anything goes" or "it's all equally good" attitude. Not at all; there's still a lot of bullshit out there that tries to pass for art. As far as Bowie goes:
As I said before, truth is that as I don't know nearly enough of his work; but, what I heard in Acman3's first clip, and some of what is on the two records of his that I own, held my interest and made me want to listen to it. That's a lot more than I can say for a lot of what's out there. Does the music of a player who has a perfectly developed tone and schooled technique but sounds like so many before him have more substance? I'm not so sure. I have many recordings of accomplished traditionalists that simply don't hold my attention. Additionally, when someone like Acman3, someone who has clearly shown to have a sophisticated appreciation of music and is not part of "the masses", says "I love Bowie" (or whoever) I have to, at least, stop and consider what it is that is grabbing his attention. I think I heard it in that first clip.
Anyway, didn't mean to get preachy about this . Thanks for the great contributions.
