There was never really a 2009 retrospective thread that I recall. Here's my "No Surprise Best Of:"
Asphyx - Death the Brutal Way: I listened to this for the first time in quite a while the other night and it really stood up well. In fact taking a break from it and coming back made it even better. An immense sound and VanDrunen (my favorite death metal vocalist) sounds as grizzled as ever. Not one dull moment in this epic. Asphyx cements its legacy. This was my favorite album of the year.
Beherit - Engram: Is Beherit the greatest metal act of all time? To come back after a 14 year break and release something this good makes me think so. However, I feel this album works best if you are well versed in the tradition of Beherit, their previous releases, and the tradition of black metal, in general. Because of this I give the edge to Asphyx for best album.
Disma - The Vault of Membros: Although Asphyx and Beherit released the better albums (and this is only a 3 song demo, of course), I am more excited about this release than anything else this year. This came out of left field for me. I would almost say I've never really heard death metal quite like this before. Great vocals, great atmosphere. Let's see what the future holds.
Birth A.D. - Stillbirth of a Nation: (not the biggest fan of thrash and the 20 minute run time bums me out, but this is just solid and lots of fun. well worth the $11. great lyrics!)
War Master - Chapel of the Apocalypse: (much like Disma, this demo makes me more excited than satisfied. love the atmosphere. Can't wait for a full length.)
Winterwolf - Cycle of the Werewolf: (nothing new here, but I'm a sucker for the style and the aesthetic. Bloody Finnish FUN!!)
If Disma and War Master can release full-lengths this year, and if Profanatica's album actually gets released, between them and a handful of Texas bands (Blaspherian, Imprecation, etc), 2010 could be one hell of a year for American Metal!
EDIT: Aosoth - Ashes of Angels deserves at least an honorable mention: no-goofing-around black metal. No lulls for 40 minutes, but not over-the-top rabid, either.
