Harmonix has released an expansion pack just for all you Metal-heads to devour.  Rock Band: Metal Track pack includes 20 scorchingly loud, ear-bleeding songs, six of which are exclusive to the game for a limited time.  The entire pack can be exported to your regular DLC collection.  The six exclusive tracks will be made available, probably around December 2009, through the regular DLC channels.  In case you missed them earlier, here are the six exclusive tracks:

• Blue Öyster Cult – Transmaniacon MC
• Hawkwind - Master Of The Universe
• I Mother Earth – Levitate
• Motörhead - Killed by Death
• Nazareth - Hair of the Dog
• Rage Against The Machine – Bulls On Parade

Right away I’m excited about the new artists on the platform.  If you haven’t noticed I’m always excited about new artists in Rock Band! First we have I Mother Earth, a defunct 90′s metal band from Toronto, has been a favorite band of mine since their debut.  I have to pay respect to my fellow canadians first.  “Levitate” is one of the heavier tracks from their first CD.  Next on my want-list are Nazareth with their classic “Hair of the Dog” which if you recall the song, contains a crazy mouth-organ-guitar solo and several mentions of a certain ‘son-of-a-bitch’.   Hey at least its not “Love Hurts”.   Finally there is a track from Hawkwind, who I had never heard of until this appearance in the game.  Apparently they are pretty obscure in the metal scene as well but they appear to have released over 20 albums in 30 years, so there are probably some Hawkwind fans lurking out there somewhere.   Rounding out the new tracks are contributions from Rock Band alumni Motörhead, Rage Against the Machine, and Blue Öyster Cult.

Altogether this is an outstanding track pack, but if you already have one or more of the songs, it may be better for you to wait until December.  The Rock Band: Metal Track Pack is available now for $29.99 USD.
