One thing you have to take into account, is how down to earth and relaxed this guys are. Romeo has his own studio, in his house. So they have no time constraint and just kind of do things. Also if not mistaken, they don't all live in New Jersey. So it was difficult to get everyone together. And I could be wrong but This all happened around 2006, when they where on Gigantour. Somewhere during the writtein process, Jason Rullo was getting married I believe, or some sort of big family thing for him. And I assume Russell was working on having a baby. Writting on the road, distance, family, and there jobs. Remember that they had jobs, they didn't just write music all day. And back to Romeo's studio, they had just got new equipment before working on Paradise Lost. Needless to say, Romeo is the man, and based on the situations in there lives at the time, I suppose Romeo was the best fit. He was probably noodling around with his new equipment and was like "hey guys I have 2 hours of music written... Lets fix'er up and record an album" The 2 hours aint just a random number either, came from Romeo's mouth himself.
And even if i'm wrong, or am not even close, the one thing to remember is. How layed back the band is, and the 4..5? year period between albums, and how they operate, which is very chilled and relaxed. They write music, because they love it. Also Pinnella and Allen where working on there solo projects, and in Allens case with other bands.
Okay... Im done lol
