FaceDown for me.
For the longest time, I just had their masterpiece "The Twisted Rule the Wicked"...and always looked for other CD's. The came out with a new one recently, and it's definitely one of the best thrash CD's of the year. I also went back and bought an import "Mindfield" for $30 on Amazon...and it is just awesome.
Great sound, phenomenal songwriting...almost art like with the tempo changes and additional elements they throw in there...and the riffage is non-stop. Probably the best constant catchy riffs I've heard from a band.
Sounds kinda like early Machinehead sorta...only angrier, more razor sharp and metal sounding...not as american...more haunting.
