If you read the interviews on the site, (
http://the.nl/nevermore ) Warrel explains a lot of the songs.
If you read on the inside of The Politics of Ecstacy album, it says:
"A young man named Christian Martenson is serving a 10 year prison term in the state of Arizona. He was set up by an undercover DEA agent over a two year period while following the Grateful Dead. Without the DEA agents involvement it is likely he never would have comitted the crime he is currently incarcerated for. Rapists and child molesters are serving shorter prison terms than people like him. The system is failing. Free Christian Martenson."
So, it talks about Warrel's friend who was put in jail for drugs. It says in an interview he wasn't a dealer or anything, he was just caught by the DEA agent.
Inside Four Walls is talking about this injustice. How more violent criminals are spending less time than Warrel's friend, a drug abuser. In part of the song you can hear Warrel say something along the lines of (I'm not listening to it right now, so I'll quote from memory) "In America today, typically drug offenders do more time than rapists, murderers, and child molestors. Is this justice? Is this the American way?"
Warrel's own words about the meaning:
Warrel: That song is about a friend of ours. The whole band is friends with this guy. He's in prison now for about ten years. He was arrested for drugs. He wasn't a drug dealer but he's gone for a long time now and the thing that makes me so angry is that there are people who commit violent crimes, that commit armed robbery, that commit rape, someone who's molesting children. These people will get out of jail before him and I don't understand why. And the only thing I can do to express the rage and the feelings I feel is writing a song about it. And hopefully that can make other people in the US think about the problem and realise it more. I mean, it's never going to change, I don't think, because the people are not in control in the US. They never have been. We pick the President and that's about it. Maybe people will think about it more, and that's the only thing I can hope for that song because it's a very negative song.
So basically, if you read the lyrics, and compare Warrel's explaination, it makes sense.
Warrel is being pretty secretive in terms of an explanation for Evolution 169. He did mention, however, that the name is indeed from something to do with chaos mathematics.
Dead Heart in a Dead World, I'm not too sure on.
Believe in Nothing is discussed in this interview:

Deconstruction I don't have a clue about.
Narcosynthesis (Yes, you guys are correct about the explanation of the term Narcosynthesis...) There is a bit of an explanation in one of the interviews, I'm just too lazy to find it right now.
