I understand that there are contemporary indie rock forums, much like Organissimo, devoted to today's rock. It would be very interesting to get the perspective of those who post heavily there to the comments made on this thread.
Let me guess---they might respond something like, "today's rock is the best, but you jazz people are so far out of it that you have never even heard of the incredibly esoteric indie rock artists we worship, which are making music which is billions of times better than the old wretched stuff that you are clinging to from your youth."
I have heard young people say things like this in response to someone who has praised 1960s or 1970s rock.
