i'm going to make a general point rather than a specific one, because i'm no doubt completely ignoring things that people probably think i ought to like.
i've actually been pretty explicit in my absolute disdain for the hippie movement, and if you look at the things i like from the 60s and 70s, there's really almost no overlap with anything "hippie" or "mod". i have a soft spot for beatniks specifically, and i am of course vocal about my affinity for punk rock, but i would have gone out of my way to avoid anything at all to do with the hippies if i had been alive in the period. i've stated this before: i would not have been at woodstock, but i may have had an initial pressing of come out.
the music from the 60s that i actually connect with was in the realm of cultural satire like zappa, jazz fusion like davis or mclaughlin, minimalist classical music like glass and reich and progressive rock like floyd and crimson. there is a small amount of more ordered psychedelic music (like hendrix) from the period that i'm fond of, but the stuff i actually like tended to be disliked by hippies, and the creators tended to dislike them just as much.
i can't stand bowie's hippie period, or his glam or disco phases for the matter, either. he was best with the spiders, or with eno. i think his high point, artistically, was actually in the 90s.
so, the reality is that i wouldn't have liked any of that stuff the first time around, and i have absolutely no interest in it at all in it's fourth or fifth incarnation, when it's gone beyond farce and into novelty territory. you should really be sort of embarrassed for your own generation's lack of creativity.
so, i'm not going to even bother slamming it as done or boring or cliched. it's just, like, "ugh, grandma rock. next.".
