Rock hasn't changed, simply the method of finding music has changed. When I was in high school, the only conduits to new music were the radio and knowing that one kid in your high school whose brother worked at the college music store. By the time I entered college, CDNow replaced that system. You could find a band you liked, and go down an internet spiral into similar bands. And, to prove my point that music hasn't changed, there are a bunch of older artists who have become somewhat popular and known (see Big Star, Nick Drake). The internet has made no huge bands but no obscure bands either, it has simply granted access.

As for the title of this thread, there are still Album oriented rock groups:
Sufjan Stevens
The Flaming Lips
