The Red Chord - Clients
Heaven Shall Burn - Deaf to Our Prayers
Job for a Cowboy - Ruination (I'd consider this death metal, some say it's deathcore, but its good so it doesn't really matter)
The Red Death - Godmakers
Through the Eyes of the Dead - Malice
Morgue - The Process to Define the Shape of Self-Loathing
These are the only deathcore bands that stand out for me, not really a fan of anything else.
If you feel the need to listen to Suicide Silence, No Time To Bleed is the better of the two albums, but thats not saying much.
DLC Wishlist: Morbid Angel, Cynic, Obscura, In Mourning, Candlebox, Buckethead, Katatonia, Dark Tranquillity, Agalloch, Gorguts
Starting albums for Voivod and Primus?
Closest thing to deathcore I like is The Faceless.
More metal in Rock Band:
Racer X- Second Heat
I didn't put a lot of effort into this review due to the fact that its my second Paul Gilbert in a row. However, I really like his guitar in this one and the singing is better for sure.
PS-Mezzanine by Massive Attack is ****in awesome
Now you can run,
But where you gonna hide from all the power of the sun?
