Every one of us has a band that they listen to regularly where there's an album of theirs that gets pretty well put through the wringer by, well, everybody... yet you're sitting there thinking "hey, this isn't that bad" (or, even, "this is pretty damn good!"). What albums are these for you?
To get things started:
Magma - Attahk: Yes, it's the ugly duckling of the catalog. Yes, there are Magma fans who don't even consider it canon. But when you have tracks that infuse elements of R&B ("Spiritual"), disco ("Liriik Necronomicus Kanht"), and even belching ("Maahnt"), the album turns out to be a fair bit of stupid fun.
Radiohead - Amnesiac: In many ways, it takes the style of Kid A and runs with it, often improving on the formula. Yet it's often considered a dud... I realize that its predecessor was a hard act to follow, but it's not like it was a second Pablo Honey or anything...
Phideaux - Fiendish: Okay, so maybe I'm a sucker for debut albums. And maybe throwing a fair bit of goth rock influence is a good way to get me to swoon over an album. Still, a couple of weak tracks excepted, it's one of the more engaging albums he's ever done, yet it's about as well-regarded amongst prog fans as 313 (the album he wrote, recorded, and produced in one day).
