Willy and Mark are two of my favourite players, love the technic, the tone, composing, great band, and J.C. Campbell is a great bass player (you'll notice him if he wasn't there).
The thing I like the most of them is the education they all have, even Randal (the vocal) has lessons to sing that way... go and check

I wish there where more bands like Lamb, inteligent non posse music with tons of attitude, but in the end I have to agree with jiujitsu_jesus, I like more Ashes of the wake than Sacrament, although Redneck sounded so much like Pantera that I just love it from the first 5 seconds of the song.
Power corrupts. Absolute power is kinda neat.
