I think RTC is hell heavy and the riffs are great but I think NMF is more refined. With NMF the songs seems to get straight to the point, Soul Evisceration is a good example of this. It kills you in the first 20 secs. Where as Cry My Name had a lot more melody and the main fast parts were the verses. I haven't got either albums on my computer at the moment so I can't listen to them at this exact point in time but I also reckon RTC had a very distinctive guitar tone because of how fuzzy and muddy it was, it was muddy in a good way, it gave the album a lot of character. The guitar tone on NMF is different to this and I think slightly better. Both albums have quite different feels to them although musically they aren't too far about. Great production on both albums.
