I've yet to go to a WAT show, and can't think of any artist off the top of my head whose WAT I'd like to watch, but I think there is one single reason to applaud that kind of thematic show: the current death of the album.

The album, especially the concept album, is for all intents and purposes dead. Not only that, I can't really imagine anyone under 25 buying any kind of album anymore. Current music is about either one-off hits or soundtracks. Music is bartered, stolen or sold for 99 cents a track. So, in that context, a WAT is a kind of reminder, maybe, of what an oeuvre can be. An album can have a beginning, a middle and an end. Songs can flow into each other. Playlists can exist outside of YouTube. I see where you're coming from, nostalgia-phobic as you rightly are, but maybe think of WAT as a kind of public service. The musical equivalent of a hard cover book as opposed to a blog.

Glad you're back.
