Yeah, as much as I respect and admire mudvayne and their music, they're still on Sony, so regardless of their own intention they're still going to be pressurized into appeasing commerciality. And i HATE the way they cut the songs down for the videos; World So Cold
(which is an excellent song, although as you said, not a fitting single/video) is only about 5 and a half minutes long, but they chopped bits out of it anyway. fucking idiots.
I don't think, however, that the actual music they wrote on End Of All Things To Come is indicative of a more commercial-minded direction. It's a genuine record with a mature feel. I don't think nu-metal is dead enough yet for mudvayne to have thought they needed to move away
from L.D.50's aggression to remain commercially viable, and in any case, they are a very creative and visionary band who are passionate about their music; it wouldn't have been characteristic of them to write L.D. 50 #2 so they're exploring a more sedate atmosphere artistically, not commercially. The guys are just too talented and too concerned about their music to sell out their vision.
