I think Apheared can attest to the fact that I am not a dinosaur. =) However, I do very much enjoy music from the 60s and 70s. For example, one of my friends just got me four CDs as a graduation gift, namely The Beatles' Revolver, The Doors' L.A. Woman, Pink Floyd's Wish You Were Here, and Led Zeppelin's Houses of the Holy. I don't yet like L.A. Woman, but I'm sure that's bound to change with a little more listening. =)
While I agree that Revolver is a good album, I don't think it's a particularly deep or (dare I say it?) "artistic" album. That is, it's very definitely pop-rock, though it's excellent music nonetheless. It's just that while it has great tunes, I find it to be filled with songs that are catchy but quite simple. There's not much to understand in Revolver.
Wish You Were Here and Houses of the Holy, on the other hand, are simply amazing. I've said on Headwize that I think the best of any type of art shows you something in a different perspective and very honestly, so that you see life in a new way. Most music, I think, doesn't really show you life in a new way; rather, it simply puts sounds together in a pleasing way.
Anyway, Floyd and Zeppelin seemed to me to really make me think in a different way; that is, it was like being high without using drugs.
Another thing I found in Floyd and Zeppelin (which I don't really find with any newer music) is that I had to listen to the whole albums, uninterrupted, from beginning to end for the full effect. It made the album itself a work of art, not just the individual songs.
After listening to this music, it's very hard for me to go back to listening to soem of the much simpler music I often used to listen to from the 90's and early 21st Century.
However, I don't think that all music from the 60s and 70s is this good; while I think Tommy, for example, is close to being as good as Zeppelin and Floyd (in terms of artistic qualities), bands like The Jimi Hendrix Experience/Band of Gypsies, The Rolling Stones, and The Beatles, may have amazing guitar-playing abilities or voices or tunes, but aren't so "artistic" in the way I've described above.
