Depends on the mood, but my current favorite:
August Burns Red - The Eleventh Hour
And I also really like:
Slipknot - Sulfur - Love it when he says "You don't always know where you stand.... 'Till you know that you wont run away!" Because it makes so much sense.
But I have too many overall favorites to list them individually or pick just one. Lots of stuff from August Burns Red, As I Lay Dieing, Lamb of God, 5FDP(LOVE their stuff), The Devil Wears Prada, Slipknot... And many others haha.
Oh, and Trimm, tight links. Good bands, and every single one of those takes much more skill than 99% of rock bands out there today.
