Excellent piece, but I would like to point out that AFI had nothing at all to do with the release of the retrospective album. That was Nitro all alone and by themselves, without AFI's consent (not that it would've been necessary, as all of the songs on the disk were recorded while with Nitro).
Anyway, great article. Took me back to one of my favorite albums of all time. Sing the Sorrow is one of the few albums I've ever called "perfect".
