Dave's series isn't finished, but I will disagree with the assertion that prog rock has been dead for decades. I do think there's a quite a lot of prog-rock-just-don't-call-it-prog-rock out there in the form of indie rock and pop. It mostly avoids some of the obvious excesses - 20 minute songs! rock operas! concept albums! - though there are exceptions to that. The Decemberists and Radiohead are probably the most obvious examples, with The Arcade Fire in there as well.
