I was just using them as one example, more a metaphor so I wouldn't have to say "all these bands from the '70s" over and over. Its not an attempt to just go after Cream. That I don't care for them is no comment on their worth or popularity to somebody else. I used to like them....first song my high school garage band did was White Room.
As I said...there's not going to be any chance, not one in a thousand, that there will be more bands in 2012 that sound like 1972, than there were in 1972. If that is the type of music you are specifically after, then by all means, find it in those bands from 1972, or 73 or 69 or whatever. I like music from a bunch of time periods and like bands from the '70s as bands from the '70s and don't need to see that in today's music. I spent all last night listening to Lee Hazlewood. There's nothing today that sounds like that. Wait, Tindersticks....Tindersticks sounds like Lee Hazlewood. But some things are just of their own time and place, and trying to recreate them is pointless when you can just go to the source, and then enjoy whatever is new and different as well, as something else.
