I've struggled for a couple of days now trying to figure out what I can say about this. It's all about the premise when it comes to this book (a collection of issues from a limited-run series).
This is a comic about one of the biggest bands of 1974, Motherfather, on what could be their last world tour -- complete with a documentary crew, a gaggle of groupies, and a manager who could be the hybrid of Wilson Fisk and Colonel Tom Parker. Like many rock artists of the time, Motherfather makes a big deal about worshiping the devil as part of their stage persona. While on this tour (possibly with some psychopharmacological help), they discover they've actually been worshiping the devil.
Things don't go all that well from there.
If you like that hook, you'll like this book. Otherwise, just skip it.
Paul Cornell wrote this, so right off that tells you this is going to be well-written. A little humor, some real people and real emotions, and some seriously messed up supernatural elements. Cornell delivers on the promise of the premise -- and a little more. It's exactly what you want to read given the hook.
As for Tony Parker? I don't think I've seen his stuff before -- but I'm going to keep an eye out for it. I honestly can't think of anyone who could've matched the style and story of this book like he did -- either in the film sections, the visions/hallucinations, or the rest. Really great work.
I should throw in a quick note here, if it's not obvious from the subject matter, this is not for kids.
It's not for everyone, but it's pretty entertaining. If the concept strikes you as up your alley, it probably is -- give this one a shot.
