My favorite opener: The Coronation. It leads you very effectively into the world and the story of the album. Which is a great one, even though its creator is not happy about it.
Understandable though - as an artist you always have the highest expectations for your own work - and if it's not 100 percent, it pisses you off because you know you could have done better - even though it is still a great deal better than all the other average stuff out there.
Off topic, I know.
My favorite closer: Child of the Wild (if we ignore the bonus track Wake Up) - simply because it is very romantic and poetic - reminding me, that Grime vs. Grandeur really is by the same band that made epic killers like Lord of the Blacksmiths, Clarion Call etc.
