Mastodon - Crack The Skye
Although not as strong a sludge metal album as Leviathan or most anything from some of the other major names in the Atlanta sludge scene, the variety of vocal styles employed as well as the introduction of more elements of progressive metal and heavy psych make it an exceptional release despite its inability to be easily pigeonholed cleanly into one specific sub-genre.
Phideaux - Number Seven (2010 remaster)
Slightly polished and reworked version of the earlier 2009 release, restructuring the album's previous sixteen tracks to ten, resulting most notably in the creation of a couple of epic-length tracks on the album's first and third acts ("Waiting For The Axe To Fall" at 19:23 and "Love Theme From 'Number Seven'" at 13:50). Am somewhat surprised there wasn't comparable consolidation in the second act, but, seeing as the album is meant to be taken in in its entirety, perhaps it wasn't necessary. The end result is more polished, but the overall character of the album changes little.
