@simao - I understand what you’re saying, but, as a musician, I think you would agree that every era of music had what may be called, for lack of a better word, a "zenith". The Baroque had Bach, the Classical had Mozart and Beethoven, the romantic had, well, whomever, the Jazz era had Coltrane. However that does not invalidate all the other artists operating at the same time. It’s more popular opinion than anything else. The US cars of 1969-70, The 396 Chevelle and Camaro, the Shelby GT350-500, the Hemi Cuda, et al, are generally considered to be the considered the zenith of US car manufacture, although I would much rather drive my current vehicle than my 1970 Mustang Mach 1 from a comfort and convenience point of view. Indeed - all the car auctions show these cars have a higher value than anything else produced in the US, AFAIK. Onto music - I think it is generally accepted that the late 60s and early 70’s were the zenith of British/US rock/pop music. You are certainly free to disagree, but I think that Hendrix/Zep et al were the fountain from which it all flowed. IMO of course. This is not to say it was "better" than anything that came after, nor does it invalidate the contributions by any major artists. So, on one hand, I do consider the 60s-70’s era to be the "halcyon" as you put it, but so what? They’re gone, the 70 Mustang is gone. Now what do we do? I really don’t know. Admittedly though, it’s difficult to accept the substitute once you’ve experienced the original.
