Here is my perspective of the story and why Viva is the best katatonia record ever!
ghost of the sun: him trying to fit into the corporation and the way the city works.
sleeper: There are 3 children most likely and their parents have died. This song is their fear of being left alone. I think the youngest the sister (which kevo pointed out to me might be the little girl on the cover) dies of a fever.
criminals: is the crime the older brother commits toward the corporation. Also it seems like he committed this crime with a best friend who got caught right there and he had to leave his friend behind.
a premonition: is him knowing he has to get out of dodge.
will I arrive: He leaves because he knows they will come for him and also his regret because the younger brother told him not to join the corporation in the first place. So he cuts his hair and changes how he looks.
burn the remembrance:is him coming to terms he has to leave everything he loves behind and also his brother having to lose him.
wealth: is the pain and regret for his greed that got him to where he is.
one year from now: he plans to go back and stand up against the corporation but then the year passes and he doesn't do anything.
walking by a wire: he goes back but is afraid that they will notice him because he's too young to be ignored so he leaves.
complicity: he goes back older this time but knows he can't waver this time and they will find out and kill him.
evidence: He checks on his brother because he wonders if the corporation found out the younger brother knew.
omerta: He meets up with the younger brother for the first time in years and years. They have a few drinks and then the older brother notices the younger brother has poisoned him. Was it because the corporation made the younger brother or the younger brothers anger for him leaving is all left up to your imagination.
inside the city of glass: The older brother is now dyeing and taking that lonely last walk through the city of glass..
